Re your motivation... just think what happens if you end up supporting an app written by morons who would need some serious effort to deserve the honor to clean your shoes. Who keep repeating mistakes we here cleaned up a decade ago. Whose definition of best practice is antediluvian. Where you'd have to explain to customers how to do workarounds for things which shouldn't exist in the first place and can be fixed by a couple of days of coding.

If you're comfortable with that scenario, go ahead.
