Adjusting lof style in acro 3.8 (list-short-width and list-caps options are gone)

Question

I am trying to compile on older document that was originally set up using acro 1.x. The document used the following settings:

\acsetup{
    first-long-format = \itshape,
    list-style = lof,
    list-short-width = 6.4em,
    list-caps = true,
    pages = first
}

On my current system I only have acro 3.8, which threw me a bunch of errors upon compilation. After going through the documentation I found the equivalents for some of the previous parameters:

\acsetup{
    format/first-long = \itshape,
    list/template = lof,
    pages/display = first
}

However it seems the following two options are gone:

1. list-short-width - Sets the width of the acronym column in the list of abbreviations
2. list-caps - Makes the written out acronyms in the list of abbreviations start with a capital letter.

Unfortunately all of my attemps in searching for a solution to adjust the column width lead me to older questions, where the solution was using list-short-width. Based on the documentation I also played a bit around with setting templates/colspec, but I didn't manage to get a working solution so far...

Any idea on how can I restore the previous behavior using aro 3.8?

Minimal example:

% !TeX spellcheck = en_US
\documentclass[a4paper]{article}%
%
\usepackage{acro}%
%
\DeclareAcronym{ransac}{
    short=RANSAC,
    long=random sample consensus
}%
%
\DeclareAcronym{sift}{
    short=SIFT,
    long=scale invariant feature transform
}%
%
\acsetup{
    format/first-long = \itshape,
    list/template = lof,
    pages/display = first
    %list-caps = true,
    %list-short-width=6.4em,
}%
%
\begin{document}%
\section{Some Text}
\Ac{ransac} is a common approach to match features like \ac{sift}.
\section*{List of Abbreviations}
\printacronyms[heading=none]%
\end{document}%

Current output:

As far as capitalisation, the list-caps key seems to have an equivalent in \acsetup{uppercase/list=true} however this key is undocumented. \acsetup{format/list=\acroupper} is probably not an intended method but will also work as \acroupper is internally the difference between \Ac and \ac.

For the list there are a couple of options with differing dependencies.

• lof can be modified through use of tocloft as described in cgnieder's answer to Space between acronym and its description when using LOF style for List of Acronyms. This matches the screenshot provided reasonably well, but deviates from the lof style that acro ships with.

• The table-based lists (tabular/longtable) also largely match the screenshot provided without modification. These default to a bold short form, due to the default templates/colspec=>{\bfseries}lp{.7\linewidth}, which can be overriden with \acsetup{templates/colspec=lp{.7\linewidth}}. We can span the full page width setting \acsetup{templates/colspec=p{6em}p{\linewidth-6em-3\tabcolsep}} (relying on calc for the in-place maths).

• tabularray may also be worth looking into as it allows the first column to be l (not requiring a hard-coded width) and the second will automatically fill, but the current (3.8) acro template is a bit awkward to customise without resorting to \RenewAcroTemplate (in the below I've left the columns as default and used a very hacky local setting of format/short=\normalfont to override the built-in \bfseries), I'm also not sure where the extra vertical space after the heading is coming from there.
