I'm bit surprised that it replaced bluez4 in this case, because last
time I tested this I also needed RPROVIDES (at least to keep ofono,
packagegroup-base-bluetooth, connman happy).

Case 2 shows that if some distribution makes decision to replace bluez4
with bluez5 (e.g. doesn't have ofono, connman,
packagegroup-base-bluetooth in their images, only their own app adapted
to use bluez5), then they need to add RREPLACES to bluez4 by .bbappend.

That's why I was complaining about "upgrade path" when someone makes
decision to change bluez version.

On the other hand, having whole R* combo in bluez5 can cause issues to
people who don't want to upgrade yet (like in Case 1) - one answer to
that is that they just shouldn't build it (no bluez5 in binary feed
should prevent accidental opkg upgrade), but this works only until
someone does e.g. "bitbake world" :/.
