Licence issues aside, if the fonts are in a personal tree they are not
available to other users. On the one hand, as somebody already pointed
out, that means they cannot be accessed so licensing restrictions may
not be an issue. On the other hand, whether the licences allow it or
not, other users won't have access even though the fonts will be listed
in the system-wide map files.

Just using sudo -H rather than sudo won't do this. sudo -H will set
HOME to the home of the target user but it won't discard other parts of
the environment so PATH etc. will be inherited and, hence, correct
(assuming they are set correctly for the user issuing the command)
whether the files in /etc have been setup correctly or not.

Or maybe the possibility. I don't know that it would be possible or
useful to document the actual failures as it seems there would be an
indefinite number and variety of these.
I've changed my sudo defaults to always use -H now because I keep
irritating myself by forgetting sudo doesn't alter HOME. This obviously
wouldn't be something I'd recommend generally.
It seems there may be no general recommendation that will work well for
everybody. I wonder about this:
as the primary recommendation.
2) Suggest that users with fonts in their personal trees should use
if the sole user of the machine.
3) Note that such users may find some configuration files interfere
with the setup.
1) sudo -H seems more robust than sudo and is probably to be preferred
on machines with multiple users. Moreover, this option is most likely
to produce usable formats. In most cases, it is possible to typeset a
document with a different font but not to typeset it with a different
format. Thus, if a user ends up with something not functioning as a
result of following the default instructions, it would be better for
that to be a personal font than for it to be an entire format. (If I
have to switch back to CM, that's one thing; if I can't use latex,
that's quite another.)
2) Users with fonts in their personal trees are likely more experienced
than those without, on average, so better equipped to deal with
complications and to understand whether the alternative instruction
applies to them.
3) Such users should be aware of possible complications.
