Warframes have Aura slots, which increases their capacity above the standard cap of 60. Primaries and Secondaries do not. Because of this most high-end builds will require somewhere from 6 to 8 Polarities in the main slots to make use of the Weapon Exilus slot, and that's assuming that the Exilus slot has the correct polarity for the mod you want.

While I'm not a fan of needing to Forma an item that much due to the resource and time costs associated with it, I don't feel that's the main issue. Polarities restrict your ability to mod your weapon in different ways. Which doesn't tend to be a problem when you've got somewhere from 4-5 Polarities on weapon, because you still have some wiggle room. But once you get up near 6 and 7? Your personal ability to have a variety of builds is hobbled. Which I think is a bit of a bummer, because it's nice to have the ability to adapt your weapon and try different strategies for different situations.

There will certainly be cases where there's a weapon and it really only has one build, and in those cases Forma-ing so that the Weapon Exilus slot can be used can make sense. But in weapons with more versatility, I don't think the Exilus slot's juice is worth the squeeze.
