'platform' tag in gamelist

What does it do or control? (see bold below)

I'm particularly interested in MAME and FBA as they are the only ones that use 'arcade' for platform. All other systems have a 1-to-1 relationship between 'name', 'platform' and 'theme'.

<system>
<fullname>FinalBurn Alpha</fullname>
<name>fba_libretro</name>
<path>/recalbox/share/roms/fba_libretro</path>
<extension>.zip .ZIP .fba .FBA .7z .7Z</extension>
<command>python /usr/lib/python2.7/site-packages/configgen/emulatorlauncher.pyc %CONTROLLERSCONFIG% -system %SYSTEM% -rom %ROM% -emulator %EMULATOR% -core %CORE% -ratio %RATIO% %NETPLAY%</command>
<platform>arcade</platform>
<theme>fba_libretro</theme>
<emulators>
<emulator name="libretro">
<cores>
<core>fbalpha</core>
</cores>
</emulator>
</emulators>
</system>

@johnodon it has to do with the scraper.
