Perhaps an alternative macro `setopt-relaxed"? Documentation should suggest contacting package authors to request improvements (it's a very slow process to get misspecified packages updated and not all authors mean what they say when they themselves don't use the customize system--this group must know this all too well).

Like what?  Would we accept, for example, a string where the type is
'symbol'?  Or any value where type is 'boolean'?

And I'm also not sure we want this: presumably, if the defcustom's
author specified a type, they meant it, no?

Which is why I asked for opinions (but for now got only yours).

Stefan, WDYT?
