Technically yes, but we have decided to post-phone changing the equalities for now.
The reason is that changing all of them could be very difficult, given that some of the current comparisons might depend on implicit type conversion. (We obviously want to minimize the risk of regressions, particularly this close to the next uplift to mozcentral.)

In the future I personally would like to change those as well, but in this first round of clean-up we decided against it.
