Now, if libsdl had been updated to 1.3, the library version probably would have changed, since 1.3 has been in development forever and we already know it's drastically different from the 1.2 series, so that would indeed have required a revbump of all ports using it.

Ok, this just went live in SDL mercurial. No more SDL 1.3. It's now SDL 2. This will mean that SDL 1.2.x and SDL development no longer block each other on macports.
Downside is that projects that use either SDL need to be configured for which SDL they should be. Not to mention that they need fixes to make use of SDL 2 instead of SDL 1.3. 
Also the 1.2.x compatibility layer has been ripped out -> more problems for projects which took the easy way to port to SDL 1.3...
