Hopefully the firmware development won't stall like it was with v4.

Rp2040 is a decent choice for relatively slow speed digital bus multi-tool, but the USB1.1 speeds will be somewhat limiting (IIRC I achieved somewhere around 700-800KB/s of serial data throughput). PIO is also flexible enough for some almost standard-but-nonstandard digital buses (for example, I used it to interface with 12-bit SPI-like interface- not many MCUs support word-widths that are not multiple of 8 for their hardware SPI interfaces).

I think it was the case that they were just running out of memory to stuff new features in and gave up on it. If so, the RP2040 will give a lot more room for this.

I have a V3 and it is a neat little tool. What isn't clear to me yet is what V5 will sell for. V3 was very cheap but this one has a display and some LEDs that will likely increase the price. Hopefully that increase isn't a big one.

I gotta say though that the RP2040 is a game changer. It is popping up all over the place, from Bus Pirates to Switch mod chips. PIO, good docs, low price, and readily available is a solid combo of features.
