Fair enough.

Actually, this flag is important to *everybody*.  Whoever thought up
the hack to use virtual blocks instead of physical ones was plain
stupid and opened the door for incompatibilities, data loss and who
knows what else.

Hence, Ferenc made the flag implicit.  Actually, he was a bit smarter
and only made it implicit when required.  Either way, the virtual
blocks are gone, thankfully.
