The Nancy Grace Roman telescope is a replacement in most respects, though it doesn't have the deep UV capabilities (HST could go down to 115 nm, Roman goes down to 480 nm). Not sure why UV isn't as important to newer telescopes, but if it was as critical to have high-spatial-resolution UV measurements, they'd probably have flown one in addition to Webb and Roman.
