I agree. People doing a tcpdump don't have to turn on promiscuous
mode, that's what the -p option is for. In other words, having
promiscuous mode disable VLAN filtering does not take away the
user's options at all.

Do you really consider that a realistic choice? Who is going to
remove interfaces that are in use just to see traffic for other
VLANs? Sniffing specific VLANs can always be done on the VLAN
device itself.
