There's a small caveat after applying this:

Before this patch, cache entries would've effectively ignored
'nnmail-use-long-file-names' (nil by default) and used long names. After
this patch new entries would honor it, resulting in an extra directory
tree for the same group. But only the original one would be opened (due
to [[./lisp/gnus/nnmail.el::;; If this direc]]). To fix it, one would
have to copy all the files in from the original directory into the new
one (and retain the active file entry). Or of course, change the above
variable (but that could have other implications depending upon one's
configuration).
