Totally agree.
On a related note: a few years ago I had a local guy build me a 5-string 1958-style Precision bass. It wasn't a typical parts bass because he carved the neck and body himself. The hardware was collected from various sources. Instead of the standard passive tone control, I decided to give the Stellartone Tonestyler a try. As an aside, the Tonestyler is a fun invention, useful to anyone who wants mid boost from a passive tone control, but here's my point: when I got my bass the Tonestyler worked opposite of normal: clockwise dark, counterclockwise bright. I asked the builder if he could rewire it the other way, but he said no. I should have realized this immediately, but eventually concluded that he had acquired a left-handed version (maybe on eBay, at a discount?)
As noted, in this case there was no option to rewire in the other direction as there is with a blend pot, but just as you said, it was easy enough to get used to the backwards control, and now it seems normal... on that bass.
A personal signature so to speak. One day someone else is gonna have the pleasure of this near mint, spectacular P-Bass. I STILL have never heard it with round wounds. (Don't get me started)
