[mcm1957]

I'm sure that

• This issue does not report a false-positive detection (use dedicated template for this)
• This issue does not request a change or removal of existing check (use dedicated template for this)
• There is no other (open) issue with the same topic (use the search!)

Description of check to be added

Using process.env should raise a warning.

Using process.env should reuire compact mode to be false. In this case eventually disable suggestion to use compact mode.
