Please include the following information in all bug reports:

• Minecraft Development for IntelliJ plugin version: https://github.com/minecraft-dev/MinecraftDev/pull/733/commits/c32a00676bfd7e84676499d9479d7104678a51c1
• IntelliJ version: 2019.3
• Operating System (this has come up enough times to be worth noting): Ubuntu 18.04
• (optional) Target platform, if relevant
  • Fabric, possible happens with others too

.ipr, .iws and .imp files are deprecated, and should be replaced with the .idea/ directory format.

I don't these files are deprecated (it's not stated in the docs), they are just "legacy", but they are unused with external systems if I understood correctly: the Gradle wizard does to not generate a .iml file for example, the plain Java and Maven project wizards do.

However I agree the plugin should not, given that it only generates Maven and Gradle projects. It seems misc.xml should contain <component name="ExternalStorageConfigurationManager" enabled="true" /> After adding it, deleting the files should be safe. A programmatic way to do it should be preferred if possible.
