Plymouth-git, splash kernel param, and boot issues - modsetting?

This is relating to the issue I was asked to file over at plymouth-git: Plymouth-git and splash boot parameter prevent Garuda from booting completely (#215) · Issues · plymouth / plymouth · GitLab.

Here is the related Garuda topic: System stuck in boot screen

I'm not looking to resolve any plymouth-git issues here, just trying to understand how modsetting is related and is it dangerous to consider in this case.

Just in case, here is the inxi:
