Obviously it’s up to you, but I wouldn’t be in a rush to replace anything just yet. I think it less likely that it’s “deprecated“ and more that there’s just a glitch during what is still a beta phase and not everything is getting correctly transitioned.
If it’s just a plain Z wave motion sensor, that should work unless someone has incorrectly entered the “fingerprint“ so it’s being paired with the wrong edge driver.
I would report it to support and see what they say.
I would also note that there were some reports about 10 days ago of problems with the smartthings Zigbee sensor. I don’t think you can assume at this point that any particular device will or won’t work, or will continue working, until the transition is complete.
You can switch from groovy DTH to groovy DTH but not from groovy DTH to Edge in IDE. If it has an Edge driver with Placeholder showing in IDE, you can’t switch it to a groovy DTH.
In order to switch, you would need to remove the device and add it back. Note: if you have a custom groovy DTH, it would install using that so if you wanted to use an Edge driver, you would need to remove the DTH.
Remember that everything Edge is currently still in Beta. some device manufacturers, including Zooz, are working on custom edge drivers, but they have not yet released them for public beta, because they don’t want to have to deal with customer frustration because of the glitches during this early beta phase.
So eventually there will be some custom edge drivers with more functionality than the stock drivers, but most of the ones from device manufacturers aren’t available yet.
There are some that have been created by community developers, just like there were with custom Groovy DTHs.
