I think the value of the special goods bonus is being a bit underrated because so many players giving feedback are on the other side of the AF to SAV grind. Yes there will be leftover charges in AF/OF; however, you'll still be able to reduce the amount of time to collect the required Orich by 20-30% depending on the level. For most players, that's a couple of weeks. Considering players are often willing to power level SC from X to 91 just to cut down on time spend in OF, i think it's fair to say a predictable reduction is much appreciated.
One thing i hadn't considered is how much players will appreciate the boost for synthesizers. When you sit in the max-age for months and up to even a year, it's easy to stockpile enough special goods for the upcoming ages. If you're starting from 0 for SAM, SAAB, and SAV goods and you're trying to race to SAJM asap, then you may not want to stay in each of those ages until you collect enough special goods to cover research for the following ages. (i.e. saving up 30k+ Mars Ore, or whatever the amount is, before moving to SAAB).
Having the option to age up and still produce a decent amount of Ore, Ice, or Carbon is actually still a major benefit for players making the FE -> Max age journey.
This GB doesn't really do much to address the needs of players in SAJM. The importance of the new GB being helpful/valuable to the players moving into the new age can certainly be debated.
As noted in my previous post, innogame knows that we're going to sell this GB to early age players anyways. This GB does actually fill the specific needs of the majority of players (i.e. not in top tier guilds + not fully developed + not at the end of the game). If I'm going to take a glass half full approach, I'd look at this as something to make a ton of "effective" FP from by selling it to early age players. We all know that early age players are going to want it far before it's useful to them. At least we can feel good selling it to someone rather than like we're ripping them off with the flying noob trap. We still get benefit from the GB by being in SAJM if we choose to play smart
