It seems libvirt's plugin needs wmem_alloc(), for example:
https://gitlab.com/wireshark/wireshark/-/issues/17889

IMO it is easier mentally to have a single library ABI policy because
we ship only public libraries. Having a more relaxed private shared
library policy would make it easier to make mistakes.

Also if libwsutil (with wmem_alloc) became private in 3.6.x then
libvirt had a much harder time continuing the maintenance of their
plugin starting with 3.6.0.

Cheers,
Balint
