To be honest I have read only a few studies on Glyphosate but AFIK the consensus is that unless in extremely high concentrations it poses no danger to either humans nor bacteria. I don't have many opinions on it, other than that it doesn't particularly cause me concern.
Antibiotic use by the farm industry IS of a concern to me, but I feel it's being addressed. Maybe not as quickly as I would like but concerns have been voiced collectively by the scientific community and changes are being made.
You are quite right that antibiotic use does change microbiome composition, however one question to keep on your mind with regards to that is. What is a good microbiome composition? What differentiates a "good" from a "bad" microbiome. The answer to that question, is "we don't know." I attended a seminar about eight or nine months ago on whole genome analysis of the microbiome, and there is incredible diversity of the bacteria and ratios of the bacteria in both healthy and people with various diseases. To this point, as far as I saw we (the scientific community) don't have a clear picture as to what constitutes an ideal biome.
I am unfamiliar with what patent you are referring to, can you clarify?
I have a lot of friends working on projects in quite a variety of areas, I know of a handful of projects that are truly fascinating and I am looking forward to seeing them get published. There are a lot of scientists out there, but as you likely well know, research is incredibly expensive (gosh reagents alone to make and test stuff are insanely over priced) and so with more people working on these things comes the need for more ways to fund the work. So while I (of course) agree and encourage people to get into research, I also know that to the outside world science often seems like a hole that you throw money into...
Be careful what you read regarding round-up, funding behind the studies is easy to hide. The industry likes tout their results from the active ingredient only and not the remaining additives that combine to do greater harm. I've seen this information out there but you typically have to go outside of the US to find it.
Good to hear we are working toward that area and it sounds like there are a ton of variable to take into consideration.
Here's the patent I posted in a reply above:
""The cannabinoids are found to have particular application as neuroprotectants, for example in limiting neurological damage following ischemic insults, such as stroke and trauma, or in the treatment of neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease and HIV dementia. "

That's the main problem I see, the research funding comes from corporate and government interests with hidden agenda, IMHO. Hmmm... there has to be a blockchain solution for this.... right? This is more in my area :)
