How much is a lot? One conversion entering the pipeline, and another
exiting the pipeline?
Any color filters that expect to operate on R'G'B' rather than RGB. I
think in most cases, these operations only work on R'G'B' to avoid the
additional conversion, but there are probably at least a few that
really do want the gamma space. They'd have to convert.
I suppose linear light is the "native" space of many (most?) common
operations. Blurring and resampling/scaling will get funny shifts
in brightness if they operate on non-linear samples, for example.
So maybe there is a lot of conversion going on already, and using
linear light could _reduce_ that? Or, a lot of conversion _should_
have been going on, and we see wonky and imprecise results because
they are missing?
Just speculating...
