The STP was originally developed as IEEE 802.1D. So how about keep this part,

and add a new paragraph like:

The 802.1D-2004, removed the original Spanning Tree Protocol, instead
incorporating the Rapid Spanning Tree Protocol (RSTP). By 2014, all the
functionality defined by IEEE 802.1D has been incorporated into either
IEEE 802.1Q-2014 (Bridges and Bridged Networks) or IEEE 802.1AC (MAC Service
Definition). 802.1D is expected to be officially withdrawn in 2022.
