They could probably do this for all of their systems. I doubt if the hardware in a Caseta dimmer is any different than Clear Connect A Ra2, Ra3, or Homeworks devices and just a flip of a bit in the firmware could change it. The problem is the marketing department. They couldn't even bring themselves up to let Radio Ra2 users to use their Grafik Eye and Grafik T devices on Ra3. Those were all Premium priced products and there is no technical reason to not do it. Yeah, maybe it would have taken them a week of dev time to add those profiles on Lutron Designer but then they already had those for Homeworks so I really doubt if would have even taken them that long. The problem I'm afraid is that a few MBAs on the top of the ladder decided that there is more money in selling new parts than to allow reuse of older parts on the new systems. I'm sure they had a nice graph and powerpoint presentation and everything with projections and such, but in this case, there is a disconnect between what Lutron thinks is best and what customers and dealers think it's best.
Ra2 came out around 2010 before LED bulbs were in widespread use, before many people even had smart phones, the cloud wasn't something the average person knew about, and overall it was a different world technically. Imagine if 5 years later Lutron would have came out with Ra3 and said nobody could use the old dimmers and that was the only way to use the app. The fact that Lutron added the Connect Bridge, updated all their dimmers, and gave new life to Ra2 showed customers that they could trust it. I really hope those people realize that Lutron has decades of trust with dealers and homeowners so in the long run, it's better to make people feel like they are investing in a Lutron product rather than just buying it and having to throw it away after 10 years.

Just yesterday I was at a Ra2 house that had been neglected by the original installer. The software was 4 years out of date, none of the timers worked, etc. and all it took to make a customer who thought Lutron was junk was to spend a few hours to making programming changes, fix the horrid programming (Half the loads in the house were in the closet both physically and in the software), and install a connect bridge to bring the system up to date. Now it's like they have a new system and love the system. That's the Lutron I like. Get out of the way of the engineers and let them make great products!
