This is true, and Maven's -e flag does reveal the likely cause:
Caused by: com.google.errorprone.InvalidCommandLineOptionException: invalid flag: -Xep:WildcardImport:WARNING
at com.google.errorprone.ErrorProneOptions$Builder.parseSeverity (ErrorProneOptions.java:288)
...
However, the implementation of ErrorProneOptions$Builder as of 2.25.0 does specifically know that the error in question is an unrecognized severity name and could say as much in the error message.
For comparison, checker names are also validated but in a different location and with a clear message (but an unclear stack trace):
Caused by: com.google.errorprone.InvalidCommandLineOptionException: wildcardimport is not a valid checker name
