npx browserslist will ignore not clauses

[Razican]

Hello, I am using this .browserslistrc file:

>= 0.15%
last 1 major version
Firefox ESR
not dead
not iOS < 10
not Chrome < 70
not Explorer <= 11
not ExplorerMobile <= 11
not OperaMobile <= 50
not KaiOS <= 100
not Baidu <= 100
not QQAndroid <= 100

Basically, I would like to drop support for not-so-used/old browsers. The issue is that when I use npx browserslist, I get the following:

and_chr 81
and_ff 68
and_qq 10.4
and_uc 12.12
android 81
baidu 7.12
chrome 83
chrome 81
chrome 80
edge 83
edge 81
edge 18
firefox 78
firefox 77
firefox 76
firefox 68
ie 11
ios_saf 13.4-13.5
ios_saf 13.3
ios_saf 12.2-12.4
kaios 2.5
op_mini all
op_mob 46
opera 69
opera 68
safari 13.1
safari 13
samsung 12.0
samsung 11.1-11.2

As you can see, there are some browsers such as IE that still appear.

IE 11 is not part of dead. Add explicit not IE 11 to remove it.

There is a possible bug with <=, but I am spending all my free open source time of preparing PostCSS 8. You will need to debug and send PR.

That didn't work either, I still get the same list. Interestingly though, in https://browserl.ist/ it works as expected.

Closing this, as I did a typo with the name when creating the file (.browserlistrc vs .browserslistrc).

It will be nice to add warning on this case
