Well, font-size and line-height both accept percentages that do the same
as the em unit. Obviously we can’t change these now, but *maybe* this is
a not pattern we want to repeat with new features?

<percentage> for zoom sounds good, but this is not a strong opinion.
'opacity' does uses <number> where <percentage> would also make sense,
but again, maybe it’s an exception.
