sqlite extensions

[tr%vispaul.me@localhost]

I realized today that the sqlite included in base has support for 
loadable
extensions[1] but, no extensions are built or included with NetBSD.

This makes me wonder:

1. Why enable this feature if no extensions are included[2]?  Someone 
needing
extensions could just use the sqlite from pkgsrc.  Should this be 
disabled?

2. If it is desirable to leave this feature enabled, would anyone oppose
including an extension? In particular the File I/O functions[3].

Thanks,
