It is well-known that Prusa is rather slow and hesitant to implement new features in their firmware because they really want new features also to work on their very old printers if possible. And Prusa really wants to avoid introducing regressions with new firmware versions (even though they are not perfect regarding this).

Thus, because of this basically promise by Prusa, the pace with which new features become available is much slower.

Prusa is for people who really want their 3D printers supported for a very long time.
