The first thing to remember is that all these proposals don't go straight into all levels of football. It's an ideas seminar more than anything, and what happens is that IF
a proposal is adopted a very low level league (park football in effect) will try it out and report back. Then you might have one of the higher level leagues volunteering to try it out for a further period of experimentation, then it'll come back to the International FA
Board for appraisal an a decision as to what to do. It may carry on being trialled, it may be passed into general play, or it may be dropped altogether.
To give an example, the idea of penalising dissent by marching the ball forward ten yards came from Rugby Union initially, was trialled in Jersey for a two year period, went back to IFAB, was trialled in the English Premier League for a further two years, and has now gone back to IFAB where the concept is going to be discontinued, partly because the rugby union concept is alien to much of FIFA
and partly because football is not a territory based game in the way that rugby is.
So, whatever gets proposed, don't panic. It's just a means of trying out new ideas and seeing if they work.
