This is unfortunately not a unique situation. Other libraries are maintained
upstream by people who don't understand proper library versioning either (and
by 'proper', I mean "the tried and true method that's been used on Unix for
years and is the known standard"). Case in point is Imlib, which recently
made a 2.0 release... and which ships libraries with the soname
'libImlib2.so.0'.
The problem with trying to correct the library names in the package is that
your packages aren't binary-compatible with third-party software precompiled
for this version of the library; libfoo.so.1 will not satisfy the dependencies
on libfoo-1.0.so.0, no matter how you push on the square peg. Likewise it's
not a good solution to call the package 'libfoo1', because the package name
should indicate the contents. libfoo1 -> libfoo.so.1. If you call the package
libfoo1 and it contains libfoo1.so.0, what happens if the next release is
libfoo1.so.1? The least-bad option that seems to hold forth is to name the
package 'libfoo10' (perhaps with a delimiter between the 1 and the 0?)... and
then petition the upstream to un-break their library names...
