Good i didn't know that years ago when setting up my vdr boxes... :)
IOW this approach has been working for me for quite a while w/o any
problems. Note i'm still at 1.4.x and my 'gaps' actually contain
adapters (unused by this vdr instance).
If the gaps really are a problem you could always renumber the adapters
using udev rules such as

SUBSYSTEM=="dvb", SUBSYSTEMS=="pci", KERNELS=="0000:00:0e.0", PROGRAM="/bin/sh -c 'K=%k; K=$${K#dvb}; printf dvb/adapter%%i/%%s 0           $${K#*.}'", NAME:="%c"
SUBSYSTEM=="dvb", SUBSYSTEMS=="pci", KERNELS=="0000:02:09.0", PROGRAM="/bin/sh -c 'K=%k; K=$${K#dvb}; printf dvb/adapter%%i/%%s 1           $${K#*.}'", NAME:="%c"

etc
