In particular, please note that upgrades from 4.3 and future upgrades from this alpha to the final 4.4 release from this version are not supported.

Although, I successfully managed to upgrade my el7 4.3 engine to 4.4 a few weeks ago... do it means it is not feasable anymore.

Correct. Upgrade from 4.3 to 4.4 will be like from 3.6 to 4.0 using backup / restore for the engine.
 
Speaking in terms of RHV (explicitely not oVirt) this means that since 4.3 has no EUS support (only 4.2) all systems on 4.3 will have to upgrade to
4.4 pretty much instantly after RHV 4.4  becomes available in order to receive further security updates if I understand this correctly.
(I guess that those with hosted engine will be in an easier position.)

Thanks for the clarification.

Mathieu
