For cores, 4 mil thick is the "leading edge" here
in the states. MANY PCB suppliers can do this.
It's below 4 mil (bleeding edge) that really starts
becoming difficult (and tricky to process at
fabrication). As Lee Ritchey pointed out earlier,
it's very easy to process <4 mil dielectrics between
cores (as prepreg). Some shops may choose that
as an option if they are not well versed with the
challenge of "ultra thin core processing".
And yes...Michael Grimm pointed out a few shops that
can easily supply the 4 mil core PCBS.
