It had also been suggested, I think, that a Farsight list could be more engagement-focused.

I hope they're wearing corrective contact lenses if they're far-sighted or those close up engagements may not go so well

The Remora was not included partly because it was released at a time when the list was stabilising and another inclusion would have stirred the waters, partly because it doesn't really have a defined role in an EA force aside from being cool, and partly because the Tau have several excellent aircraft choices anyway and the Remora was more designed to support AI than EA.
