- because by default applications trust either a large, promiscuous
set of certificate authorities, or even worse, use the operating
system supplied list of trusted authorities.

- because by default applications do not or cannot utilize mitigating
measures like perspective based certificate retrieval and consensus
from varying endpoints or sources.

- because by default applications may not support robust cipher suites
or handle some aspects of protocol or session negotiation poorly /
incorrectly / insecurely.

- because by default applications don't support a persistent, mobile
store of trusted server certificates built up over time, which a proxy
could provide (Tahoe LAFS / encrypted $cloud storage for your
certificate store available wherever you need it.)

- lots of additional reasons...
