The way I interpret it is that if you have multiple ways of super-accepting, such as bidding a suit suit to show a super-accept and a doubleton in the bid suit, then you should alert all your super-accepts.

But if you play the simpler method where you simply jump to 3 of the major when you have a max + 4-card support, and it provides no other implicatons about your shape, then that doesn't need to be alerted because it's natural and has the expected meaning.

I agree that a transfer with a jump reply in the target suit is a relatively "natural" convention, but it's not an integral part of the standard Jacoby transfer and it might be argued that it would only be really "natural" if the transfer promised enough strength to make the jump a reasonable risk when playing rubber, whereas many of us bid transfer on 0 HCP garbage.
In any case the EBU does not seem to allow your interpretation:
Blue Book 2017 4 H 2b (f) said:
4 H 2 Because they have a potentially unexpected meaning, players must alert:
...
(f) The completion of a transfer that shows a specific holding in the suit bid

I'm not sure how the EBU views it, but in the ACBL, negative inferences like this are generally not alertable.

The laws make it clear that negative inferences derived from agreed conventions must be disclosed to the opponents: it's up to the Regulating Authority how this is acheived. EBU seems to make some clear pragmatic choices. In Italy the FIGB says that any conventional bid below 3NT must be alerted, with no concessions made for common conventions, period. But of course there is always a grey area, particularly when a conventional bid coincides with a natural bid (like a Stayman reply showing a major), or when a natural bid had a conventional alternative, and it just wouldn't be practical to alert all inferences linked to actual or possible conventional bids. Nor is is realistic to expect club players to have full system notes.
