Are you using newpm with PGO? FWIW, we've also ran into bloated inlining multiple times after switching to npm a while back, but most of that turned out to be due to a combination of npm's better use of BFI for inline and some kind of profiling issue leading to unusual flat profile which makes inliner super aggressive (flat profile has a relative lower hot threshold so more callsites are considered hot).

We haven't found problem with inline deferral so far, though we also haven't measured its perf benefit..
