For articles currently being written, the authors should obey the
instructions to authors and use the journal's current package. But there's
a big backward compatibility issue. E.g., there are many older papers on
arXiv.org. When a widely used package is deleted from CTAN and TL, these
papers are no longer compilable without the source files being edited.
To see the scale of the problem, I googled for "elsart.cls" in
site:arxiv.org and got over 1900 hits. (Elsart.cls is one of the class
files in the now-removed elsevier package.)
It seems to me that a good policy is that a widely used package should
normally remain on CTAN (and TL) even when obsolete.
