No, because those get scanned by R CMD check and friends.

For the one you do not want, Heather's suggestion was spot. Supply a new
(cleaner) system-wide default.  Those values are not checked.

I sometimes do the opposite and add (what would be "non-portable") options in
~/.R/Makevars to make very noisy builds quieter etc.

As we said no issues as nothing not allowed by R here.
