Everything except history.production.min.js should be un-minimized

[jfirebaugh]

In the 5.1.0 published package contents, all the .js files are minimized, even history.development.js. This makes inspecting or debugging the installed package difficult. (Yes, there are .map files and //# sourceMappingURL commments, but those are unlikely to make it through a bundling pipeline and asset server intact, and they don't help with inspecting the contents of node_modules/history on the filesystem.)

Only history.production.min.js should be minimized, as that is the only file that's documented for direct use in a <script> tag. Everything else will be going through a bundling pipeline, where the user will decide when and with which tool to minify. This is consistent with the practices of other prominent packages which include both *.development.js and *.production.min.js files, e.g. react.

Aside from the fact that the map files are malformed and don't work. You don't need minimized libraries. The packaging/bundler software will minimize them and create map files as needed.
