Only if it ends up working properly. The commit you reference above
(which removed the PCI_MULTITHREAD_PROBE option), is fine, pci
multi-threaded probing is still broken as it is a model that PCI drivers
are not yet ready to handle properly yet.
Why do you want it to be enabled again? It shouldn't affect you doing
multi-threaded probing for some other subsystem.

No, it turns out that no matter how hard and loud you put the warnings
in the config file help, people will ignore it and enable the option
anyway, and then get mad at you when your machine breaks just like the
config option said it would.
It also upsets other developers who get blamed for bugs that were caused
by this change, not their code, making debugging very difficult.
So it should stay removed for now.
