So just two more than me: desktop, which I don't use and ispell which 
I don't pre-start the sub-process.

I could inhibit messages for those two but it seems a little messy.
I'd rather not inhibit generally in case there are issues, I'd have to
do it in each of my files so that I'd still see loading timings.  I could
do it for recentf and repeat-mode but that feels like working around
their specific behavior.

I'd kinda like to inhibit stdout and leave stderr, to put it in those terms.
IMHO the above seems like unnecessary information. Yes
it's specific, but it's also of little use.  I enabled repeat-mode, I expect
it to be enabled, I don't really care that 23 commands and 9 keymaps
were affected vs some other number of commands; and I don't need 
help like "see describe-repeat-maps" every time I enable it.
