And I'm probably disagree with you but let me explain below.

The release schedule for 4.13 is really short (4 month). With the feature 
freeze in approx. 1.5 months, see [1]. 

As 4.13 will be one of our last release in the 4 era I think we should be 
quite sure that we don't break anything or even more to be 110% sure to have 
fallbacks, migration, APIs for Nepomuk apps to access Baloo data etc.

And even though I know that Vishesh is doing a great and a hell of a job I'm 
not too sure if one single person can manage all of this (not just the 
implementation but I think it needs a lot of testing as well).

IIRC it's still not clear for all the current Nepomuk apps if they work after 
4.13. Let's try to list them again.

- Amarok (got Nepomuk support with 2.7, will it work after 4.13?
- Digikam (gets new Nepomuk with 4.0.0 due in May or so. Will it work)?
- Dolphin
- Gwenview
- Conquiere
- KPhotoalbum
- Kamoso (seems so be ready in time)
- Kdenlive (out of the most popular KDE apps, with some man power problems 
atm, ok, but nonetheless)
- Nepomuk-webminer and Nepomuktvnamer
- Plasma Active/Plasma mobile with Share-Like-Connect

And another question. Will people who used Nepomuk extensively lose data? I 
know that Nepomuk was one of the most hated software, but there were and are 
people who like(d) and love(d) it.

So in conclusion I think that a change of Nepomuk to Baloo in 4.x without a 
100% (very very well tested!) migration plan and testing is a no-go (from my 
side, just me). I've the strong feeling that such big changes are for 
something like kf5 and a port of the apps to kf5.
