Since rxjs 7.2.0 most operators have been moved to rxjs

With RxJS v7.2.0, most operators have been moved to 'rxjs' export site. This means that the preferred way to import operators is from 'rxjs', while 'rxjs/operators' export site has been deprecated.

It would be nice to have (fixable) rule, which makes sure you only import from rxjs

For example:

import { map } from 'rxjs/operators';

Should be

import { map } from 'rxjs';
