It requires more precision than Swype, but GBoard supports multi-word word deletion if you swipe back originating from the backspace key. You get some haptic feedback, and can scrub to adjust the selected boundary.
Unfortunately some of those Swype nicities are patented [1], so other keyboards can't use them.
