If I understood correctly the initial thread message, Jakub's main
concern is that if he creates a datacenter, then all storage domains
have to be of the type initially chosen

Taking from rhev 3.1 docs:
"
The type of data domain dictates the type of the
data center and cannot be changed after creation
without significant disruption. All storage in a data
center must be of one type only. For example, if
iSCSI is selected as the type, only iSCSI data
domains can be attached to the data center.
"

So if he would like to put iSCSI and SAN LUNS on the same DC, he can't
at the moment.

If I remember correctly in another past thread it was said (Itamar
perhaps?) that there wasn't a particular restriction or design
constraint about this limitation, but probably only historical
reason.... is this true?

So it could be cool to put on the roadmap the chance to mix several SD
types in the same DC.

BTW: Jakub which is the kind of replication / network raid 1 you are
using or planning, perhaps drbd or similar?
