# Changing \parskip in List of Abbreviations (glossaries)

I am creating a document, in which I need a List of Abbreviations. I liked the style alttree, so I use it.

Now, I want to change the distance between the entries in the LOA, so to say change the \parskip value locally.

I found a solution myself with the help of an answer to this question, which is shown in the MWE below. Problem: neither am I sure that this does not potentially crash something else, nor do I know if its the best way to do it, so these would be my questions here.

MWE:

\documentclass[12pt,a4paper]{scrartcl}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{lmodern}

\usepackage[acronym, nomain, nonumberlist, nogroupskip]{glossaries}

\newacronym[sort=WHO]{WHO}{WHO}{World Health Organisation}
\newacronym[sort=EDS]{EDS}{EDS}{Energy dispersive spectroscopy}
\newacronym[sort=ABC]{ABC}{ABC}{Alphabet}
\newacronym[sort=LaTeX]{LaTeX}{LaTeX}{Lamport TeX}
\newacronym[sort=Acr]{Acr}{Acr}{Acronym}

\glsfindwidesttoplevelname

%%%% This here is the part I added
\newglossarystyle{modalttree}{%
\setlength{\parskip}{6pt}
\glossarystyle{alttree}%
}
%%%%

\makeglossaries
\begin{document}
\printacronyms[style=modalttree, title={List of Acronyms}]

Result with alttree-style (former result):
Result with modded modalttree-style (MWE above):
