I've committed a change to texinfo.tex (2023-04-04.21) to implement
a new @link command.  Please try it and see if it is what you want.  It
is experimental and could change.  If this is a success we could implement
it in texi2any as well.

Example usage:

\input texinfo

@node One
@chapter ONE

tralala

@page

@node Two

@tex
\gdef\linkcolor{0.1 0.5 0.05}
@end tex

A(@link{One, text})B

A(@link{One})B

@xrefautomaticsectiontitle on

A(@link{One})B

A(@link{Introduction,,bash})B

A(@link{Introduction,Bash,bash})B
