Sure, it would be easy to bypass this since there is no UA enforcement, but this would be limited to a fairly small technical crowd.

I think it is useful for UAs to have this information. Even if we don't 
make it "mandatory" for UAs to enforce the size restrictions in the 
spec, some might choose to.

A large majority of users will never bother bypassing the restriction, 
either due to lack of skill or time. Even if UAs did enforce it, it 
would be possible to bypass (in Firefox at-least, via an add-on). I 
don't anticipate that to be a huge issue, as long as we cover 90% or 
more users having a good experience for apps on any device.
