I didn't say "a good reason", I said "if we can solve the issue in
some other way".

What problems are those?  You mentioned grepping the files, which can
be easily handled by excluding the tutorials directory from the
search.  Are there any other problems we should consider?

"Gracefully" is in the eyes of the beholder.  It's true the support
for renames improved in the recent years, but there are still commands
that either fails or need special invocation methods to work across
renames.  So it's still a source of inconvenience and occasional
failure or mistaken conclusions, and I'd like to avoid that if
possible.
