Just making subversion happy to use older Sqlite versions may introduce
working copy incompatibilities if you share working copies between different
clients (and sometimes OSs). The Sqlite database format is part of the
repository format and will be part of the subversion working copy format.
And if different binary packagers choose different versions we may introduce
extra incompatibilities later.

3.6 still defaults to the 3.0 compatible database format, but it does have
support for a later format.

On my primary development OS, I use at least three binary distributions next
to each other which all compile their own depencies. (TortoiseSVN, AnkhSVN
and a commandline client). In my very specific case I'm responsible for
compiling two out of these three, but I can imagine cases where many more
binaries are used next to each other by users who control none; especially
using some of the commercial subversion clients on Windows and OS X.

I would prefer to limit the amount of supported sqlite releases per
subversion release (Maybe 3.4+ for 1.6 and 3.5+ for 1.8, etc.) to make sure
working copies for a single version are always compatible. Using the
amalgamation version of sqlite in our release would make sure we always have
a compatible working copy/repository format.
