No one, it's not even sure this repo is linked to Linus. It seems to be just a copy of https://git.kernel.org/pub/scm/editors/uemacs/uemacs.git/

Does Linus use macros with uemacs?

I like the simplicity here, Jasspa's microemacs has similar simplicity together with tons of functionalities - ideally something like Jasspa could be further polished/developed ...

This is uEmacs/PK, an enhanced version of MicroEMACS 3.9e. So the macro/script engine is kind of outdated. Daniel Lawrence made significant changes to macro support of MicroEMACS until version 5.0, I believe Jasspa branched out of MicroEMACS at a later time than uEmacs/PK. The good thing about Jasspa is that they get approval from Daniel Lawrence to re-license from non commercial use to GPL, while uEmacs/PK (this repository) is kind of stuck in license limbo (probably still non commercial).
