Funny, the workshop manual, true it is a single one from the 80s, has quite detailed interval tasks listed. And the detailed instructions later, identified by task code. On top of that, it includes all / most steps regarding diagnostics. And, obviously, detailed instructions regarding repair and replacement of bits and pieces. I never bothered checking those manuals for modern cars so, first I don't do that work and second there is only so much one can do anyway.

The right to repair move started because lately it is difficult to impossible to perform some repairs by yourself and there is a lack of documentation accessible to owners. Yes, in the '80 you got specifications, manuals and guides for most cars, almost none today.
