Anyways Google has license agreements to include LTE in android as it needs it for AT&T and Verizon phones. It wasn't because of these licenses they excluded LTE from the Nexus it had more to do with Verizon being a pain in the ass to deal with not to mention the added costs of having to add a CDMA chip to the device. It was just easier to go with GSM for now and include LTE in the Nexus 5 next year when more carriers actually have it.

Doesn't work that way, the FCC has to certify the device for LTE operation. You can't just grab some parts and start broadcasting in certain frequencies without a license and CERTIFICATION
. The Nexus 4 is NOT a LTE certified device and therefore operating as such is illegal (at least in the USA).
Check out the certifications for any phone on FCC.gov and you'll see certs for WIFI, GSM, UMTS and LTE seperately if they have all of them. GSM in 850mhz can be fine but UMTS in the same frequency is all screwed up and causing interference which is bad and therefore the device wouldn't be certified for the USA (via FCC).
- Check the FCC Test Report - It only shows, GSM, WCDMA, WIFI, BT, NFC.
Here you can see the AT&T LTE Samsung SGS3
- Look at the SAR testing which clearly shows LTE being tested
While I don't that's why they removed them, i'd say it's a good guess.
EDIT- If you are still not convinced here's the LG Optimus G for AT&T w/LTE
Mentions LTE in the report (click Test Report) since it was tested for and certified for LTE.
