While this is true, the USRP1 also did not need to be reloaded every time

the one for UHD.
I can confirm that the relevant .rbf files are the same between what I
just downloaded via "build-gnuradio firmware", and what was
shipped with Gnu Radio 3.2.2:
Gnu Radio 3.2.2:
MD5SUM FILE

Fetched via build-gnuradio, installed in /usr/local/share/uhd/images
mere moments ago:
MD5SUM FILE
=====================================================
7744fe9a8fa7b3009d16789fb5309ae8 usrp1_fpga.rbf

The *filenames* are different, but the images are the same.
Pretty sure it's the same story for the .ihx file that is the USRP1
firmware for the on-board FX2, although it *may* have been recompiled
under a newer SDCC since Gnu Radio 3.2.2, not sure--in which case,
the .IHX files would almost certainly be different.
When the UHD interface for USRP1 was put together, it was decided not to
make any changes to the platform itself, but rather to have
UHD make the existing interface "work" with UHD, and certain UHD
features are "emulated" for USRP1.
