Why would you automatically start install on any computer that does
network boot? You can configure PXE server to not do that.

Yes, it was. The behaviour changed when bootindex was introduced. I
think it should be easy to switch it back to what it was for -boot
option, but -boot is/should be deprecated in favor of bootindex anyway.
Implementing opt out from boot process for bootindex is doable but more
involving.

One can argue that having such brokenly configured server in your
network is dangerous anyway. What about physical computer that can be
trashed before you even realize you had to disable network booting in
the BIOS?
