I do have to agree. I do read feedback and comments on the mod, and the high difficulty (especially without saving, but really, saving is a technical problem, unlike difficulty, which is a design problem) seems to be a turn off for a lot of people. Which is kind of a shame considering how much more the mod is advertised lately, judging just from the repeated reminders of the mod's existence on Twitter and Facebook. (And of course, the amount of effort.)
One thing I really learned since getting a gamedev job, is that difficulty is one of the most pivotal reasons people would quit and never finish a game, causing an incredible lost of sales just thanks to word of mouth. Of course, this mod is for free - though personally I think it would worth the money - so sales are of no concern, but would be still great to see it succeed, and known by many.
I do hope that in BR2, the Easy and Normal difficulties will be something most people can complete, especially if the Save/Load system will be restored till then.
