I think it’s a terrible idea. Some people have reasons for naming things as they do. “That’s what’s on my bottle” is a perfectly legitimate point to make and a perfectly legitimate reason for them to keep that name in their stash. Other people have custom flavors that they mix as a stone, a dilution or create as an NET. There’s no way to standardize that.
It makes more sense to create categories. 1 - Standard name 2 - DIY and 3 - uncategorized. This way all the non standard names will get dumped into #3 and we can sort to exclude them the same way we sort to exclude single flavor recipes.
At the same time, we could be able to set our defaults when entering our stash. The same way we can check the box “Use manufacturers specific gravity” we can check the box “use standard naming conventions” at which point the drop down would include only the standard versions.
