Verizon DSL question (actually TCP & MTU)

[lots of people discussing MTUs and TCP efficiency]

Ah, it was my understanding that all modern TCP implementations used
path MTU discovery.  By initially setting the don't fragment bit and
watching for ICMP error packets they can quickly find the largets
possible MTU which can be used without IP fragmentation between two
computers.  Is there some reason that fragmentation even matters here?
The real problem seems to be that PPPoe uses a small MTU resulting in
poor data/header ratios.  I suppose there might be some NAT gateways
which don't handle this properly...
