It's still a bit vague.

Changing the buffer's syntax table just for `prettify-symbols-mode`
would likely encounter resistance (since it's likely to introduce
regression in other parts of the code), but if it comes with
corresponding updates elsewhere to accommodate that change (and those
changes don't make the code worse), then it might be acceptable.

Of course, as I pointed out, it's not necessary to change the buffer's
syntax table just for the immediate needs of \alpha and \beta in
`prettify-symbols-mode`.  But in order to accommodate more TeX-style
code it might indeed be a good idea (or not: I can't say without
spending more time investigating the issue).
