Pretty much yes, as we can't change existing functionality without
breaking things that are working properly.
There are proposals for how to fix up the capability mess, it just
requires someone to do all of the dirty work in implementing it.
Or use user namespaces, in a container, which should give you good
enough confinment to not need to worry about capabilities anymore.
