The so called ‘academic’ knows the square root of fuck all if he thinks something being outside the limitation period is a loophole. Limitation periods are mandated in statute, and followed by bodies such as UEFA in the interests of justice and fairness to all clubs that are subject to its rules. They exist to provide certainly around litigation and require parties to commence proceedings within a prescribed time-limit. They are apparent to all parties involved from the outset, and cannot be imposed retrospectively.
They bear absolutely no resemblance to a loophole. They are (in the context of the UEFA charges) a well-established, widely understood, unequivocal, mutually agreed term of the contract between the parties.
They are also taught to law students at a very base level.
I have never heard a competent lawyer describe a limitation period as a loophole, and nor have I ever heard one describe their deployment as unfair. They are widely accepted across the legal profession as both manifest and a hard and fast rule - something to be closely observed and treated with respect, especially in the contemplation of any litigation.
How could something with those characteristics ever be described as a loophole, unless you didn’t know what you were talking about?
