First, thank you for this discussion. About the sage pip install project. The problem is that I don't know at all what will be available. But if you are done with sage's pyx files in src/sage/libs then it should be similar with giacpy_sage.
It is indeed rare for an spkg to be linked to the sage library and giacpy_sage is more similar to the cython files in src/sage/libs than to an external package. The original ticket https://trac.sagemath.org/ticket/15226 six years ago about giacpy_sage was a sage patch. It just ended with no answer but with the current giacpy_sage it is still easy to put 4 files of giacpy_sage in sage's source tree src/sage/libs, adjust src/module_list.py and let sage's setup.py build giacpy_sage. Then you don't need an external package at all. This is related to Vincent's question. There are many cython files in sage/libs related to cypari2. Currently giacpy_sage have none. We need one of the following (to not lose any features) either giacpy_sage is an external package linked to the sage library or a part of giacpy_sage (or all of it, because it is just few files) is inside sage. Any of these solutions is fine for me. But being in between is more work and my skills and time are limited. The python package have a different name: giacpy. This was the only request I had during the previous vote where all the focus turned on giac and where giacpy_sage was forgotten. (cf https://groups.google.com/d/topic/sage-devel/HI0uZra5_iI/discussion) I don't see any conflict in having both. Sage could load the python package but it is just less interesting than loading giacpy_sage. A minimal python is able to use the giacpy package obtain a full computer algebra system. I don't want to break this with the in between solution (1 python package and files in sage). It is important for me that a window user with no development tools looks to be able to do with a minimal python installation: python -m pip install giacpy and have it. It was very difficult for me to provides these binaries, and I don't want to break this. giac and sage are both computer algebra systems, so there have have many interactions that are meaningless in a standalone python. Another remark: giac is a standard package and giacpy_sage test it more. For instance this ticket https://trac.sagemath.org/ticket/27306 was a giac bug in a new version of giac. It was not related to giacpy_sage and I guess that it would have been detected during the upgrade of the giac package if giacpy_sage was standard, while it was detected after.
