Well, it's about what you bring to the BA table that's important.
You can do 7 x SOF-SFO TP runs for say £10k and earn 5000+ tier points, but at the end of the day, that's little in the way of spend.

I personally let myself drop from GGL. Not spending ££££££ or in control of budgets etc., so as with the majority of GGLs (I'm guessing), we're unimportant. Never felt GGL offered anything beyond a phone number (used twice since Covid and they hung up on me half way through one call, the second was 50/50 in usefulness terms), and a handful of CCR / Chelsea visits - Gold / Emerald pretty much covered anywhere else. Other than a few times flying AA, there's not been anything recognition wise from BA (ok, a couple of welcomes onboard in the last 3 years or so, but I had a few more, still single figures though, when just gold, or pre-Covid).
