The Problem with XY Generations Code Card Redemption Limits

I have a question regarding the code card redemption limits for XY Generations. Unlike most sets, XY Generations never had individual booster code cards. As such, you can only get Generations packs by redeeming various special products, which are currently subject to a limit of 4 codes per product, greatly restricting the total possible number of boosters you can obtain from code cards. Currently, even if you own 4 code cards of EVERY single specialty product ever released for XY Generations, the total possible Generations packs you would receive would total 232 packs, which is far lower than the 400 for all other sets. Is this an oversight or working as intended? If this is an oversight, can you raise the redemption limit for XY Generations products? Thanks!

Unlike regular expansions, Generations booster packs could not be purchased individually from booster boxes. Instead, they were only made available in special 20th Anniversary-related items of merchandise, which included Mythical Pokémon Collections and Red & Blue Collections. Each Mythical Pokémon Collection comes packaged with 2 Generations packs, in addition to a special Full Art promotional card and collector's pin featuring 1 of the 11 Mythical Pokémon available as part of the 20th Anniversary distributions during 2016. The Mythical Pokémon Collection—Mew was the first of these products available from February 22, 2016, concluding with the Mythical Pokémon Collection—Meloetta in December 2016, mirroring the distributions. Each of the 4 Red & Blue Collection boxes available throughout 2016 contain 4 Generations packs in addition to either a sculpted figure or Jumbo card of the focal Pokémon, depending on which country the product was made for sale. Two other Generations products were made available later in 2016: the Generations Elite Trainer Box was released in July and the Super Premium Collection: Mew & Mewtwo was released in September. Each booster pack contained 10 cards, which comprised of 8 cards from the core Generations set and 2 from the Radiant Collection subset.
