This would work for large TRIM requests. However, TRIM requests are at block granularity. To properly track, which stripes have valid data, MD would need to store for each block whether it has valid data. Otherwise, it cannot tell whether some TRIM request has removed the last used block from a stripe.

Yes, it might be a nice addition, but it's added complexity, and it would need somebody to step up to the plate and implement it (plus it would require mucking about with the layout - there may or may not be somewhere to store the fact that stripes are empty or in use).
Cheers,

And, not being a storage device, MD does not see this as its responsibility.
