Optimise selected animation curve(s)

Would it be possible to add a tool that can optimise selected regions of animation curves (i.e. removing unneeded keyframes where a value isn't changing, or optionally maybe even curve-fitting to reduce the number of keys)? Currently I'm doing this manually to help trim the .riv file size down when an animation's finished and ready for runtime, but it'd be nice to have an automated way of doing it to save time and avoid accidentally deleting something important.

Apologies if such a feature already exists and I've just missed it!
