Xes, you are right. But what happens when one of your RAIDs get really
corrupted because of a multiple disk error, e.g. through power failure.
Because you have one large filesystem you loose all recordings. This is
the same as with the standard VDR recording distribution. Because of
this I have modified VDRs strategy so that each managed filesystem is
first filled before going to the next one. And I migrate all files
including meta files of cutted recordings always to on partition.

If the link support of VDR is dropped then the only solution is to mount
partitions nested into the directory tree. This very bad if a error
occurs and it is also very inconvienient if a disk runs full. Just think
about having a genre directory "Action". You have mounted a disk partion
to it and it is getting full. If you add a disk you have to either add
it as "Action1", or you have to mount it elsewhere and use symbolic
links on the old "Action" volume to get access to the recordings within
the old structure. Both is not nice.

I know that most people would be happy with the much easier handling,
but as VDR more and and more extents its functionality in direction of
video server, dropping this feature reduces data placement flexibility
considerable. This also limits the possibilities to limit data-loss on
disk and filesystem failures.

IMHO, it would be better to fix the delete algorithm.
