So I would! :)

I strongly    agree.

I strongly disagree. :)

Yes, it can. As I said, suppose your OS is Linux 64 bits and you
installed TL 2019 and, later TL 2020. At any time, you can run:

  │ /usr/local/texlive/YYYY/bin/x86_64-linux/tlmgr path add

(YYYY being either 2019 or 2020) to retrieve the symlinks of the TL
install you want.
