Why you need to be able to add links between two pegs already on the board

Here is a variation from a game I recently played.
https://cf.geekdo-images.com/images/pic3240745_md.png
It is purple's turn. On this server, I could remove the H5-J6 link and then play i5 linking to H7:

But if I did that, yellow would win immediately with J4:

Under standard rules, the only way for purple to win is to place a peg at i5 and do *not* remove the H5-J6 link, do *not* add a link from H7 to i5 *on this move*.

yellow cannot prevent purple from adding the H7-i5 link later. Play might continue with yellow playing at K4 to prevent purple's double link from i5 to J6,

And now purple wins with -i5'/H'6K6 (using Alan Hensel's notation at http://www.ibiblio.org/twixtpuzzles/[url=http://www.ibiblio.org/twixtpuzzles/]http://www.ibiblio.org/twixtpuzzles/[/url])

But such a move is not possible on the TwixtLive server, because there is no way to add a link between two pegs already on the board.

Of course, this pales in comparison to the importance of adding the swap rule, but I thought I would mention it anyway.

if it were possible to add links like that, then the rule should be: immediately, any and all pegs that can be linked because of a line being removed should be linked, thus giving the opponent the ability to set up for a link in the event their opponent removes a link.  This would prevent a player from making 2 or more links in a single turn without the opponent being able to passively defend while not their turn.  The balance in TWIXT lies in the 1 dot / 1 link potential per turn.
