Review of behaviour: exporting imports about ethereumjs-util

Here are my assumptions:

• we're only exporting what we're using internally, nothing extra added on
• the types exported are guaranteed to behave the way we expect to inject
• different versions of the modules exported should still work, within reason
• we're mostly doing this for people who havent figured out how empowering an automated dependency graph is -- its for producing bundles that such users can copy-paste in - and not having to say "oh and also go get a bundle for X and Y so you can use this properly"

Thats my thoughts. Not sure what change you are suggesting. Using the exported modules is optional as it works with your own versions, so I see no problem here. Though, do clarify your concerns.

I understand the motivation behind that would be code size when processed via browserify. Is that really a problem?

No this is not a problem

Shouldn't browserify work out it as long as the modules in the dependency chain use the same version of the imports?

yep!

There are two reason for the current behavior

1. as @kumavis to help some front-end devs that didn't use npm
2. it make keeping all of the common ethereumjs-* deps versions in sync, easy.

Will transfer this to organization (will delete ideas since this never caught off and it is already challenging to maintain one organizational repo).

This is reduced to the question around the ethereumjs-util re-exports, will move the issue there.

I think we have found a good balance here with dropping the cryptosecp256k1 reexport with v7 in #249 and keeping the BN.js and rlp reexports. Especially the BN.js reexport turned out to be very useful and somewhat needed after some experiences we made along the BN v4 to v5 switch which caused major incompatibilities when we partly switched some libraries here. The rlp reexport is not so strictly needed eventually and might be up for discussion, not really some urgency here though.

Will close.
