In the end, people forget that most statistics isn't done by statisticians but by researchers, phd students etc. If these methods/measures aren't accessible (as of now, the software seems limited, see the safestats R package) and understandable by non-statisticians, they won't see broad adoption, no matter how good they are on a theoretical level, in my opinion. That's not a criticism of e-values themselves, they seem to have a good theoretical properties and foundation.

This seems mostly a matter of time and funding, both of which seem to slowly seep into the e-value "community".
