So, if the variable MyVar contains a ”/”, sed will fail and a

variable ”MyVar” must not be changed in any way, other than that,
everything is allowed, I suppose…

I'm not aware of an elegant solution in sed. You can do this in awk
however:

awk -v MyVar="${MyVar}" '{ gsub( /\$1/, MyVar ); print }' -

Basically -v allows you to pass a shell variable into an awk variable,
which removes escaping concerns.
