Hi Thomas, First of all, thanks for the review!

Ok, got it, thanks for the specification.

Great, maybe I'll include explicitly that I want these tasks to be 
stretch goals.

Got it, I'll definitely include that, thanks!

I was looking at the official GSoC timeline to have a reference, but I 
understand that the project could extend till November or something like 
that. I have a lot of flexibility in that sense, and I would be happy to 
work on it for a longer period.

According to that, do you think it would make more sense to define it as 
a large project? I would be open to that. In that case, I would keep the 
current tasks as the core goals, and extend the work to additional 
OpenACC features depending on progress.

One concern I have is that, given the proposal deadline is close, I may 
not be able to like fully specify the newer OpenACC features 
implementation (Or yes?), maybe in a very abstract way.

Thanks for the input!

Best,
Sebastian
