That would be yet another way to push ?This web site was designed for
800x600, 16 colors, IE 5.5 or later.? ? only with the added ?feature?
of ?sucks to be you, get a bigger screen, this content will not
display?. UA sniffing, now even worse! Oh, I would certainly be mad.

This is an interesting case ? but today well handled by minimal sites.
OkCupid, Twitter, Wikipedia all have well-known minimal alternatives
that can be used when on a bandwith-constrained connection. Often, they
are arguably better (not full of ads etc.).

Since that type of request is not narrowly constrained to specific
circumstances (e.g. location-based services), there is a possibility
for this to become very annoying.

Externalizing the inability to provide content that works across
multiple devices is a very easy cop-out for developers. I for one
advocate control at the UA level (like with CSS media queries) so there
won't be yet another UA string nightmare.

Also, I am writing this on a laptop via a throttled mobile connection.
