I usually update all my project files to the most recent version, or archive them as MIDI 1 files, if applicable. I never take the fact that projects done in early versions of DP will be supported indefinitely (not to mention, my entire plug-in scheme was switched around anyway when I went from a PPC machine to an Intel machine that doesn't support non-UB plugs and VIs -- some plugs and VIs were actually discontinued altogether, some were change radically, so I've dealt with plenty of plug issues in DP, anyway). As I rarely, if ever, use the stock DP plugs or VIs, my main concern is keeping my third-party AU plugs and VIs up to date. Unfortunately, I have a few audio/MIDI projects that were done in Vision DSP, which is why I also have an incredibly slow iBook in my office that still runs Classic 9.2.2, OMS and, God help us, FreeMIDI, until I can get them (re)mastered and archived as sound files with silences and MIDI 1 output files. Nothing on that machine is supported anymore. But that's my point: you can't assume something won't radically change down the road and cause your favorite software to become something else to change with the times and the technology.
As for DP taking the "professional" route and leaving their backward compatibility open-ended, it may ultimately not be up to them. Like I said, Apple's already killing support for PPC, and if they also refine the AU architecture, MOTU could possibly decide to focus support on Intel machines and Intel-only operating systems, and maybe even decide running AU native is more cost- and processor-effective than running it under an MAS wrapper. If so, where does that leave MAS? Whether it runs on Intel machines or not, it's an audio system contiguous to one program on one operating system, unlike VST, VST3, TDM or RTAS, which share similar programming on multiple platforms and, at least in the case of VST (and UB AU), inside multiple DAWs.
