Thomas E. Dickey added it with others in the prerelease for 20180127 6.1, see:

	$ less +/xterm /usr/share/doc/ncurses/NEWS

and they are in the current Cygwin package terminfo 6.1-1.20190727, which is in
Base category and always installed/upgraded (many of the xterm+* entries are in
dependency terminfo-extra and disable the capabilities enabled or set by the
corresponding xterm-* entry):
