Thanks for the input, @jamiebuilds. I'm familiar with the controversy. It's not an easy change to make without breaking things and we have limited resources on this project, but if someone would want to offer a pull request that makes this change in a backward compatible way we'd consider merging it.

SMFH, the giant company box has limited resources? "we'd consider merging it" cool.

@kennetpostigo $2B ain't enough to afford find-and-replace technology these days

In order to keep the backwards compatibility, we'll create new interfaces with the new naming convention. The existing interfaces will be supported for a pre-defined transition period. We have started working on a a design for this.
This issue will be fixed in the next major release of the product.

Thanks for bringing this up. @jamiebuilds
