[pluginutils] (or any other rollup part) should not depend on "blatantly non ESM" modules

[pkit]

• Rollup Plugin Name: pluginutils
• Rollup Plugin Version: HEAD

Expected Behavior / Situation

Compiles in browser

Actual Behavior / Situation

Does not compile, because picomatch is a cjs-only module with no default export.

Error: 'default' is not exported by https://cdn.jsdelivr.net/npm/picomatch@2.2.2/index.js

Modification Proposal

picomatch looks abandoned (typed proposition hangs for 9 month already), just replicate the functionality within plugin itself.
I can probably create a PR if you want.

Thanks for opening an issue. Unfortunately this is not within a reasonable proposal. Plugins are intended for use at development-time and not at runtime. If you are attempting to use any during runtime in a browser environment, please use a compatible compiler.

[pkit]

Use case is codesandbox-like in-browser dev env.
Where custom rollup.config.js should be able to load and transpile correctly.
Although I think what I really need is just a commonjs plugin without the load() hook.
Thanks.
