pros/cons of wiring sensors to can talon srx

[loafdog]

Hi,
My team is using can talon srx first time this season. We are running low on dio ports on roborio. We are tossing around ideas to avoid running out of ports and one idea is to wire some sensors directly to the can talon srx. We are thinking of encoders and limit switches mostly. Maybe a pot. From what I can tell, we can read these sensors using can talon class and use the values in our robot code. Even if we don't want to use any close loop control on the talon. To me it looks like a no brainer method to avoid running out of ports. And I like having the option of running closed loop control on the talon if we so choose. We would have to purchase breakout boards/wires and figure out how to hook up the sensors directly to talons. Learning about that is the only downside I see so far(if you can call learning something new a downside).
Any other downsides?

Thanks.
