in the light of 1246 I discovered default target is es2025 and it only es* targets are expected. underlying webpack does support node* as a target, but ncc restricts it. but using es version as a target doesn't make sense for nodejs versions, because es support is fragmented.
I'd like to relax es* only target restriction to include node* as well, to make GitHub Action build artifacts smaller by not transpiling everything to es2015 but rather only to what's missing in node20 for example
