Google could have added MTE for a couple of years now, but apparently don't want to force it on OEMs as part of their Android certification program, it is the same history as with OS updates.

Don't the Pixels have MTE? Definitely GrapheneOS does, at least to some extent.
Kind of, you need to enable it on developer tools, also Pixels are Google's, not the other OEMs.

to be fair, most of MTE's benefit is realized by having enough users running your apps with MRE enabled, rather than having it everywhere.
This is because MTE facilitate finding memory bugs and fixing them - but also consumes (physical!) space and power. If enough folks run it with, say Chrome, you get to find and fix most of its memory bugs and it benefits everyone else (minus the drawbacks, since everyone else has MTE off or not present).
trade offs, basically. At least on pixel you can decide on your own
