While Williams is watching from Gloucester, former Wales and Ospreys forward Jonathan Thomas has returned from England.
The 42-year-old will lead Swansea in Super Rygbi Cymru after previously coaching at Bristol, Worcester and Ealing Trailfinders.
Thomas was at the Whites at the start of the regional rugby era in 2003 and went on to win four titles and an Anglo-Welsh Cup with Ospreys.
“The players who are international players won’t worry too much because they know they’re going to end up with a team, whatever that looks like,” said Thomas.
“It’s the young players or the players that aren’t international players. It’s terrible, there’s a level of anxiety because it’s a short career, there’s no guarantees and an injury could stop you at any time.
“The uncertainty is not helpful for players to bring the best out in themselves.
“It’s also not good for the recruitment. When you’re trying to plan and recruit as a coach, as a head coach or as a CEO, it’s an impossible job if you don’t know what the format and the finances are going to look like.
“The sooner we get clarity on all of that the better as a whole for Welsh rugby.”
