The typical definition of a "closed low" is defined by Recon finding winds from at least 4 different directions nearly perpendicular to their flight path.

I'll take exception with the above description, as I think it is confusing and irrelevant in this situation, as recon never went into 90L. But while recon never flew 90L, the feature has pretty much been closed off for several days. Recon is helpful, if not sometimes critical, when a system is far out at sea. However, once a given feature approaches land, ground and sea-based anemometers can be clustered together in enough abundance, as to get a very clear picture of what is going on at the surface. That has been the case with 90L for at least the past 18 or so hours .

90L struggled to retain deep convection over a significant portion of its LLC. Around 2AM last night, NHC increased their three-tiered guidance to a "High" probability of an upgrade, but by the time 5AM came around, the deepest convective flare-up with an associated MCV was back to being displaced to the LLCs northeast, after what looks to have been a brief pairing-up earlier in the overnight hours.

The same sort of situation occurred once again as 90L made landfall, with a short blast of apparent mid and low level co-location. This, too, did not fare well for long.

The wind speed/pressure relationship at the surface , closed surface low, warmer core, and other determinants do argue that 90L was riding the line, and that post-season reanalysis may deem it reasonable to include it in the official count, but as with many things, some calls are just more subjective than others.
