acronym package to capitalize the first letter of the short form of the acronym

[LauraElCam]

In the package acronym in latex there is only a command that capitalizes the long form of the acronym (\Acf) but I want to capitalize the first letter of the short form of the acronym. Do you have any solution?

Could you please specify any use case for this enhancement proposal?

Sure... I want to wirte an acronym in capital letters without showing the full form.
`\documentclass[a4paper, 11pt]{article}

\usepackage[english,italian,german]{babel}

\usepackage{acronym}

\begin{document}
\begin{acronym}[Bash]
\acro{eq.}{equation}
\end{acronym}
\acs{eq.} should be written with a capital E.
\end{document}`

I'm actually not too picky about terminology, but "eq." is an abbreviation, not an acronym. However, an acronym is a special case of an abbreviation. The reason I asked is because pretty much all acronyms are capitalized. Exceptions might be some trademarked lower case styled acronym thingies (eSATA, for example), but these would also be written in lower case at the beginning of the sentence.

I think you're more likely looking for a package like cleverref (or \autoref from hyperref) if you're interested in references to equations, etc. It can also use the abbreviated forms, e.g. "eq." instead of "equation".

Edit: In my opinion, it is also somehow bad practice to introduce commonly known abbreviation in the style of the acronym package. Something like "See fig. (figure) 1..." doesn't look nice and it feels like the author thinks you're stupid. A more unobtrusive way would be to add \items to the acronym environment, which in fact uses a description environment.

\begin{acronym}[AAAA]
    \acro{RA}{random acronym}
    \acro{ARA}{another random acronym}
    \item[eq.] equation
\end{acronym}

Moreover, there are numerous statements which advice against the use of abbreviations at the beginning of a sentence, e.g. https://www.editage.com/insights/scientific-writing-avoid-starting-sentences-with-a-number-or-abbreviation.
