Combining Lumen & Static light(maps) would be amazing!

So I found <this> post refering to a <livestream> where @DanielWright concluded that combining static lights and lumen was not a useful combination…

I just wanted to throw my 2 cents into this discussion.

Currently with Lumen, it’s still hard to produce environments with many lights, since each non-static light has a significant performance impact. This puts a hard limit on how many lights are feasible to use when using Lumen.

This limit would very much go away if we could combine Lumen with lightmaps. Performance-based switching would also become feasible this way (simply switch off Lumen for mobile, without having to make two completely separate lighting setups, for example).

It would generally be incredibly convenient to have, say, Lumen for the sun/skylight lighting (so you can have dynamic time-of-day, and all the other benefits) and baked lighting for the rest.

Moreover, since both technologies are already developed, shouldn’t it be relatively easy to just “add” lightmaps to the total Lumen result? I suppose Lumen reflections are more complicated, but in the livestream they said this part is on the roadmap anyway.
