How can I avoid MnSymbol to redefine the bracket parenthesis?

Question

I'm trying to save the definition of the square brackets since the package MnSymbol redefines it. I think the redefined ones are aesthetically ugly.

I'm looking for a solution similar to this. A simple and understandable solution is preferable.

How can I apply that solution to the parentheses definition?

\documentclass{standalone}
\usepackage{graphicx}
\usepackage{MnSymbol}
\begin{document}
with MnSymbol:  \scalebox{2}{\Big[42\Big]}
\end{document}

That one is pretty understandable (wait, in this case you're trying to do something else, namely preserve the font of a big delimiter.) — user202729, Dec 31 '21 at 07:22
Do you want to use all of mnsymbol except that delimiter, or only one or two symbols from mnsymbol? — user202729, Dec 31 '21 at 07:23

MnSymbol is not just a collection of additional symbols; it changes all of them in a style that’s appropriate to accompany Minion, not other fonts. If you don’t use Minion, you don’t want to load MnSymbol. — egreg, Dec 31 '21 at 09:04

This solution isn't particularly straightforward, but it works.

Open LaTeX source code (e.g. in source2e.pdf) and copy the relevant lines. Modify largesymbols to oldlargesymbols to avoid problems.

%! TEX program = pdflatex
\documentclass{standalone}
\usepackage{MnSymbol}
\DeclareSymbolFont{oldlargesymbols}{OMX}{cmex}{m}{n}
\DeclareMathDelimiter{[}{\mathopen} {operators}{"5B}{oldlargesymbols}{"02}
\DeclareMathDelimiter{]}{\mathclose}{operators}{"5D}{oldlargesymbols}{"03}
\begin{document}
without MnSymbol:  $\Big[42\Big]$
\end{document}

The high-level documentation of the font-setting commands are in fntguide.pdf.

Doesn't seem very elegant as you have to copy paste code, while you should be able to avoid? – user202729 Dec 31 '21 at 08:51
Although it looks like that LaTeX has a very complex system to select font on \everymath built on top of TeX's font select system, I haven't been able to figure out how to e.g. get the current font. – user202729 Dec 31 '21 at 14:00
