downsides to replacing xfce4-terminal?

[Lee <ler762@gmail.com>]

background:
There have been two things preventing me to moving to Debian -
horrible scrollbars & no right-click to paste in the terminal

xfce4-terminal v0.9.1 finally has right-click = paste
  https://gitlab.xfce.org/apps/xfce4-terminal/-/commit/970905924ad685827cee2b2406a3b8a6b6990187
so what are the downsides, if any, to replacing
/usr/bin/xfce4-terminal with the one I build from the xfce4-terminal
0.9.1 source tarball?

If it makes a difference
$ cat /etc/debian_version
11.2

Thanks
Lee
