Agreed, we are currently with an inconsistent **.gitignore **
We first have cache/* which ignores only files directly at the first level of cache dir.
Then later on we have cache/ (under Browserstack section, which is misleading for the current purposes) which ignores everything that the above ignores, and further ignores all the levels below…
Note this old article is a bit out of date, but not completely: The cache directory and why you can’t just delete it

It’s important to read it before any considerations about the cache directory. Although I think all that is more relevant to the decision of when to delete the folder or not, and is probably less relevant (or irrelevant) to the gitignore decisions we’re discussing here.
