extensions – incorrectly flagging internal package imports

[TehShrike]

With an eslintrc containing this rule configuration: 'import/extensions': [ 1, 'ignorePackages' ]

a file containing an internal package import:

import dep from '#dep'

is incorrectly being flagged as a violation of the rule.

warning Missing file extension for "#dep" import/extensions

Indeed; these aren't supported until the resolve package supports them.
