In writing docs I noticed that some directive targets support implicit rules patterns as dependencies (e.g. .NOTINTERMEDIATE) while others don't (e.g. .NOTPARALLEL).
Would it be considered mandatory for e.g. .ONESHELL: %.o to be supported? Personally I never use implicit rules because static pattern rules are just much less confusing generally, and it looks like implicit rule pattern support will significantly complicate the implementation. Static pattern rules (with e.g. $(OBJS) as dependencies of .ONESHELL and a corresponding static pattern rule) work fine with what I already have. It would probably be pretty easy to arrange for an error message with a hint about what to do if per-target .ONESHELL with patterns is desired (use a static pattern rule). Thoughts?
