I should have made it stand out more clearly that I didn't suggest that
this particular case was related to the statement of limited manpower.
The statement about limited resources is merely my personal conclusion
why only the current version receives bugfixes and why there's only one
previous old stable version which receives security/data corruption
fixes (I haven't heard that statement directly from any SVN developer,
but I always took it for the being the logical reason --- I might stand
corrected though).

Well, if it is like this, then I might have gotten a false impression.

That said, thanks for the clarification of how you understand the
statement. I'll certainly take that into account and might propose
bugfixes for non-security/-data-loss issues in the future, if I feel
strongly enough about them.

Rergards,
Stefan
