You need to follow some engineering standard. If your engineering org is not optimising away vendor lockin, blocking someone from using tailored-feature-number-367 is unlikely to have any positive effect and you'll just make everyone move slower. If avoiding vendor lock-in is something the org cares about and is doing properly, yeah sure, enforce it, otherwise I've seen many people fighting windmills on this and bikeshedding about "not getting locked-in" when effectively many other things already lock you into that vendor.
