The meteor/tools/isobuild/resolver.js changes are the static half of the
puzzle. The runtime half was implemented in install@0.13.0 with this
commit: 233aa75ce3
Supporting "module" in package.json for server code is not advisable
because Node.js will be adopting the "type":"module" convention instead,
and in the meantime we need to maintain consistency with Node's module
resolution rules, which only currently pay attention to "main":

I recently noticed a bug whereby modules transferred from the application
bundle to the modules bundle would lose their application-specific import
extensions, since all modules installed in the modules bundle have only
.js and .json as import extensions, matching default Node behavior.
This commit fixes that bug by emitting one meteorInstall call per distinct
meteorInstallOptions object. This logic would work if every module had a
different meteorInstallOptions object, but in practice the modules bundle
should end up with exactly two meteorInstall calls, because a single
options object is shared among all modules from the same source batch.
This only affects newly created applications for now, but developers can
update to the latest meteor-node-stubs by running
meteor npm install meteor-node-stubs@latest

As illustrated by #9554, if a custom .babelrc plugin such as
@babel/plugin-proposal-optional-chaining imports a missing dependency such
as @babel/core, that failure causes inputFile.require to throw an
exception that looks a lot like @babel/plugin-proposal-optional-chaining
itself is missing, which can be confusing.
This change does not fix the underlying problem (the @babel/core package
still needs to be installed), but it does expose the exception so that the
developer can do something about it, rather than merely leaving the ?.
syntax uncompiled.
Here's the offending line of code:
47ce7e71c9/packages/babel-plugin-proposal-optional-chaining/src/index.js (L2)
Unfortunately, depending directly on @babel/core seems to be the policy
for Babel plugins, per this PR: https://github.com/babel/babel/pull/6778
