I suppose that even the 2-3x difference--requesting 256 MB and actually
getting 512 MB over different APIs--is acceptable, since to users,
requesting storage is an order-of-magnitude question more than a precise
number.  As long as implementations are still allowed to implement separate
quotas if they want, it's probably acceptable for this API to not reflect
them precisely and to be biased towards a shared quota.

actually care.

That's interesting; reducing the amount users are nagged about things that
they probably don't care about is important.  It would also need to suppress
prompting from calls to requestQuota if the quota increase would have been
allowed automatically.
