I'm not fond of creating a defcustom to work around what I consider
as a simple bug and to configure something which the user can already
configure with a two-line mode hook addition. So I won't do that
change myself.

I don't use many other editors but I can tell you that online editors
like the ones found at hackerrank.com, which I strongly suspect are
based on LSP + treesitter behave as if electric-pair-mode was on
and electric-indent-chars is just '(?\n). I.e. they auto-indent
on newline and don't bounce around when symbols such as ':',')' or
';' are typed. As far as I can tell, auto-indenting on characters
other than newline is an Emacs invention that only works well if a
mode has near-perfect predictive powers of indentation, which
c++-ts-mode clearly doesn't have (yet).
And then my personal opinion is that it is an annoying
feature to have on by default as it whole lines about.
Having electric-indent-chars set to '(?\n), like c++-mode
has, is fine.
