The order produced by the current public release of scalafix (.* after .Phase) comes from the fact that sorting was done using _ internally (Scala2 dialect). Indeed, .* & ._ are not on the same side of .P:

scala> Seq(".*","._",".a",".P",".{}"," ").sorted
val res4: Seq[String] = List(" ", .*, .P, ._, .a, .{})

I'd argue that it's better to keep alphanumerical tokens together (no matter their case), so that order of * is accidentally better.

The output of this PR on these specific lines is consistent with scalafmt, for all rewrite.imports.sort values, so having wildcards first seem to be the right thing to do.

version = 3.7.17
runner.dialect = Scala3

rewrite.rules = [Imports]
rewrite.imports.sort = ascii
rewrite.imports.groups = [
  [".*"]
]

version = 3.7.17
runner.dialect = Scala3

rewrite.rules = [Imports]
rewrite.imports.sort = original
rewrite.imports.groups = [
  [".*"]
]
