How many MLA Fee-waived cards is too many?

I started deep diving into CCs back in 2018 after I learned about the AMEX Plat fee waiver. I'm under 5/24 and thinking of picking up the Chase IHG Premier card (because of course I am because Army). The issue is that I've built up a ton of very high annual fee (AF) cards over the last ~five years, and I'm starting to worry that Chase or AMEX at some point will decide that the amount of perks I'm gaining annually while avoiding paying literally thousands in fees is too much and I should just get dropped. Is there any data points that show specifically that covered borrowers (i.e. active SMs) who accumulate so many cards eventually just get their whole accounts shut down? I don't mind if I get denied, but I already get so much value out of my account. I don't want to push it. If it matters, my wife basically has all of the following as well. Together we have ~30 CCs.

I have:

• Five major AF AMEX CC/Charge cards
• Three major AF and two minor AF Chase cards
• One SCRA CaptialOne card
• One Major MLA-covered Citi card
• Sixteen total CCs
