This reminded me that a SIGWINCH will update $COLUMNS and $LINES,
and therefore tput and $COLUMNS and $LINES will be more reliable
than echotc/echoti/$termcap/$terminfo.

I don't see this as a problem for $termcap/$terminfo. They are supposed to
return static values from external database; so far you have the same
problem when using original functions (tgetstr etc). E.g. curses has
special variables that held current lines/columns values.
