This may be the dream but is not and has not been the reality of rooting phones and flashing them with custom software.

It's ugly, it's error-prone, and the software that attempts to simplify it doesn't and is of unknown trustworthiness. A very unhappy path.

Absolutely not a reasonable option for the typical user, and an even less reasonable expectation that they should do it or should have known to.
