Not dumping the roms would put the board at much higher risk going forward than the little tiny risk you have with removing socketed roms. All the roms are way past their lifespan for holding data. It's amazing that the data can still be extracted if the roms are original. A miracle. The first thing any sane tech would do is dump the roms.
It's amazing to me that people think they own the data on these, like own the copyright. Haha.
