DeprecationWarning: Use of deprecated folder mapping "./" in the "exports" field

See original GitHub issue

When building with tslib, I’m seeing the following on every build:

(node:40688) [DEP0148] DeprecationWarning: Use of deprecated folder mapping "./" in the "exports" field module resolution of the package at <snip>\node_modules\tslib\package.json.
Update this package.json to use a subpath pattern like "./*".

I’m pretty sure this started when upgrading to Node 15.1.0.

Environment:

Angular CLI: 11.0.0
Node: 15.1.0
OS: win32 x64

Package                         Version
---------------------------------------------------------
...
typescript                      4.0.5
webpack                         4.44.2
tslib                                 2.0.3

This is an Angular project - I can provide a repro case if it’s not obvious.
