IMO it should be taken back to the good old days when offside was simply a player in an offside position...end of!
That has never, ever been the case. There is no time in the entire history of the Laws that it has been an offence simply for a player to be in an offside position.
I've published this before but here's my "offside screed" again.
"Even from the very beginning, the original Laws issued in 1863 did not call for a player who was in an offside position to be penalised, unless he were to ''touch the ball [...]or in anyway whatsoever prevent any other player from doing so.'' (Although they didn't use the term ''offside'' back then, instead it was called being ''out of play'').
From then on, down the years there have been several occasions when the law-making authorities have issued specific instructions to referees or included wording in the Laws, to emphasise the point that a player needs to do more than just be in an offside position, to be guilty of an offence.
For instance, in 1903 the FA Council issued the following statement: ''It is not a breach of Law for a player simply to be in an off-side position, but only when in that position, he causes the play to be affected.''
Also, in the LotG issued in that same year, the phrase ''interfere with [...] play'' was used for the first time, in relation to offside.
In 1910 the FA council stated: ''Some Referees award a free kick when a player is simply in an off-side position. This must not be done.''
The following wording was included in the Laws document in 1920: ''Play should not be stopped and a player given off-side [...] because the player is in an off-side position. A breach of the Law is only committed when a player who is in an offside position interferes with an opponent or with the play.''
In 1956, Law XI International Board Decision (IBD) 1 was issued, stating that a player who was in an offside position should not be penalised if it was clear to the referee ''that he is not interfering with play.''
In 1978 the laws stated: ''A player shall not be declared off-side by the Referee [...] merely because of his being in an off-side position.''
And ever since 1997, the very first sentence of the Offside Law has been: ''It is not an offence in itself to be in an offside position."
I hope this makes it clear that there has never been a time when it was an offence simply to be in an offside position.
