​Actually this is a great question for this list .. how many implementations were created?
1.) The original 1978 version that shipped with V7 and 32/V (BSD 4.1 and 4.2)
2,) PC-UUCP for DOS came next -- I never knew how much was ripped off from the original, because at the time, the Chesson's G protocol was not well specified.   The authors claimed to have reverse engineered it - I will say it worked.
3.) Honey-Dan-Ber rewrite - most popular for a long time
4.) Taylor UUCP first real clone that I know of that I do think was done with out looking at other's source.  G protocol had been publicly documented by then and the Trailblazer in fact was shipping with the protocol imbedded in it.

Any others that folks know about and how well were they used?  Did things like Coherent have a UUCP?   Linux and FreeBSD were able to use to Taylor UUCP because it became available by then.    Whitesmith's Idris lacked anything like UUCP IIRC (but was based on V6).   Same with Thoth originally at Waterloo, but by the time they shipped it as the QNX product it was V7 compliant but I do not remember a UUCP being included in it.    Minux lacked a UUCP as I recall, but I'm hazy on that has Andy's crew wrote a lot of the user space.   Coherent was a "full" V7 clone and include things like the dev tools including yacc/lex and was released much, much before the Taylor version came out -- so what do they use for uucp if at all?

Coherent came with a modified version of Taylor, IIRC. At least in the later versions; I don't know if they had something else earlier.

Does anyone remember any other implementations?

One or more microcomputer BBS (Bulletin Board System) platforms had UUCP support to bridge their store-and-forward messaging networks to USENET and send email, etc. The implementation I remember off the top of my head was Waffle, written by Tom Dell. Waffle later became the basis for the "influential" (however one chooses to define that...I think they mean that in the same way as the WeLL is considered influential) Mindvox Community/early ISP in New York City. I'm sure there were others in that niche, but I don't know of any off the top of my head. The whole BBS thing is mildly interesting in its own right, more as a social phenomenon rather than technically, though.
