We're talking about VMs, and UEFI is noticeably many times slower to boot.

Everyone will have different experiences: mine is that UEFI on a VM is still quicker than BIOS - Tianocore and kvm work perfectly well.

BIOS is _dead_ in the sense that new hardware doesn't support it, it's not being developed - and when Linux eventually is forced to move to attestation by market pressure it'll be dead anyway.

Although I've a 25 year old laptop somewhere in my junkpile - I'm hardly expecting to resurrect it - and it's been some years since I've _needed_ BIOS (except for a couple of HP Microservers which are annoying in that firmware is a paid for support contract upgrade).

Which environments are you testing this in? It doesn't match my experience at all - we transitioned all of Google's internal cloud desktop environments to UEFI without anyone noticing.

Google also ( almost to the date ) 2 years ago made Unified Extensible Firmware Interface (UEFI) and Shielded VM the default for everyone using Google Compute Engine and provided migration path from on premis uefi based vm images into that environment.
