does new checker's rules TOTALLY same as original checkstyle rules? if not same, please desc what different between two of them. there are too many check to avoid wrong code and ensure easy reading in checkstyle rules, u should impl all of them in new checker before remove checkstyle rules.
furthermore, u should explain the purpose of replacing spotless with checkstyle

• import-control is done through replaceRegex Add remove wildcards imports when formating and ordering imports. diffplug/spotless#649
• Suppressions.xml is not required under the spotless plugin.

Other rules can use spotless directly. If you have any other verification rules that you are interested in, please send them to me.

[morrySnow]

checkstyle is not just for code format check. it is also check some code logic check. for example,

• ensure no fall through branch in switch statement
• ensure switch statement has default branch
• name name overload method should put togather
• must have java doc for long method
• ...

does spotless do same check now?
