I am mostly worried that the risks for the network effects due to a potential chain split could far outweight the marginal benefits provided by BIP110. As I said I don't mind the signaling, but not at the cost of damaging the network effect. I would have been much more comfortable to signal if it had not been of the UASF. I would be fine with BIP110 activating with 90% support or failing with 5% support, but I would not like it if it activated with low but significant support.
