If it's ported...

Maybe this feature is worth delaying then?

Let me point out the obvious here: We can discuss possible quality problems 
for a few more weeks, *OR* we use the time to actually test the code on a 
wider range of systems. This way we wouldn't have to guess so much about 
possible impact to other apps, and we can judge much better how ready Baloo 

Don't see Baloo as a third party service that someone else has to fix and 
debug, rather get on the train, test it, report your experience and make it 
possible to get it solidly working.

There's no Plasma Active release planned based on 4.x APIs, so this one can 
just be ignored until there's a clear and concrete roadmap. Likely, the next 
Plasma Active release will be folded into the Plasma workspaces anyway.
Besides that, Plasma Active will be benefitting a lot from Baloo, since it's 
typically run on smaller devices. The pain here is limited since there are not 
too many users currently, and the parts of the system interfacing with Nepomuk 
(and Baloo in the future) are rather well defined.

I think this question has been answered a few times already, even in this

I'm not strictly against this. Actually, we have some lenience with the long 
term support workspace out, so we can recommend people to use that, if they're 
slightly more adventurous, run 4.13, if they are completely mad, help us 
getting Plasma 2 in shape. That's quite a nice array of options. Communicated 
in the right way to our downstreams, this helps us to avoid problems.
