Have there been any plans for this?

I have a custom reporting tool using the API that will build out how much time has been spent each month, and then uses the estimate for planned time in the future.

The problem is balancing if the estimate field is for future work, or for the original estimate since we'd like to keep track of that as well.

I can't rely on the estimate vs the logged amount since some tasks are in progress as a "we estimated 8, we've worked 5, so the planned total is 3h remaining", but some tasks are "we estimated 8, we worked 5, I'm just about done let me update the estimate to 30m left so my manager knows what to plan for next week"...and now I've lost the original estimate of 8h

While a custom text field could work, I rather not have to parse every coworkers updates if the field is 8, vs 8h, vs 8 hours. We should be able to have a time field that we can set one or the other to base against, so for original estimate vs the current estimate, we know our time differences for work planning and billing, and potentially if we want to comp any time to know are they paying the full 8, the worked 5, or somewhere in between

We estimate times of tasks using the "Time estimate" feature. But we also need to track "Estimated time remaining" WITHOUT modifying the initial time estimate.

A time field would be really useful for our organization. We have work for events that need to happen at specific times.

The current time tracking feature is decent, but it would be far more useful if the tracked time could be added to a custom field. This would allow us to use formulas with time tracked, time estimated, and other values to calculate key metrics for our teams. Right now, the only way to access time tracked data is through dashboards, which offer limited options for building detailed metrics. Adding time tracking as a custom field would open up many more possibilities.
