It's all inherited from the recreational market, strain names are made by the original breeder - and if they're ever removed, it's like effectively anonymising the medication and removing credit from them.
There are very very few strains that were actually ever initially bred with medical-use in mind, and 95%+ are all just companies profiting from illicit creations (less so in recent years with it being legal to grow in several countries/states).
The industry has gone wild several times about strain names, and it does make many clinicians uncomfortable too - but I honestly don't see any other alternative without either discrediting the original breeder, or anonymising the history of where strains came from.
