Is this actually a spec limit?

Yes,
In "9.4.2.161 Transmit Power Envelope element" of "IEEE Std 
802.11ax™‐2021",
It show 4 types in "Table 9-275a—Maximum Transmit Power Interpretation 
subfield encoding".
And it has 2 category for each type in "Table E-12—Regulatory Info 
subfield encoding in the United States".
So it it totally 8.
