Sure, but it tends to be significantly more work. Upstreams need to support
several platforms at once, so they often cannot just move to new libraries
and drop support for the old ones, and some are also quite picky about code
style issues that ultimately do not matter to end users.

Well, that is exactly why it is harder to make a patch that is acceptable to
upstream than one that works in the distribution. A downstream patch can
even be conditionally applied, if you want to support old and new library
versions in the same specfile, so the dual support need not be in the patch.
This is of course not the case for an upstream patch. So then you end up not
only adding "#ifdef"s for every line you changed, but also need to add a
build system ("configure") check for the library version. It can turn a
quick search&replace job into a patch adding dozens of new lines of code.
