nope, it seems like U-Boot has different kind of checks. For example my
testing unit has following U-Boot:

 U-Boot 1.1.4-gbec22107-dirty (Nov 18 2020 - 18:19:12)

and flashing from OpenWrt back to stock with latest factory vendor image
works as expected:

 Firmware downloaded... filesize = 0xeeae77 fileaddr = 0x80060000.
 Firmware Recovery file length : 15642231
 Firmware process id 2.
 handle_fw_cloud 146
 Image verify OK!
 Firmware file Verify ok!
 product-info:product_name:Archer C7
 [Error]sysmgr_cfg_checkSupportList(): 1023 @ specialId 45550000 NOT Match.
 Firmware supports, check OK.
 Firmware Recovery check ok!
