I think we just have to accept that terms mean what people use them to represent, and not always what they started out meaning or what the etymology would lead us to believe.
Pantheism, is for most pantheists a non-theistic doctrine. That is what the term is generally used to represent these days, even though at other times, the understandings of it were a bit different.
We can fight the tide of language usage, but it might be a losing battle.
We can make up terms that we feel are more accurate or appropriate, but we can't force the general population to adopt them. Time will tell which terminology wins out.
Some people may have issues with any "god" concept,and feel they must personally distance themselves from anything that might be construed to suggest they believe in such a higher power. We all have to choose labels we can live with and are comfortable sharing.
Language is powerful, and I fully understand people's wanting to be careful with it.
