I agree. My thought was such 2-for-1 kits would be strictly for very temporary, situational use in an emergency only. The idea of making kits in advance was simply that in such an emergency having staff scrounging adapters and tubes is it's own cost and have a kit that's ready and been at least a little bit thought through makes this a little more likely to succeed. I was also hopeful, as discussed in the Reddit thread by docs who know a lot more than I, that filters and optimal routing could help minimize cross-contamination. It also appears from papers released in the last few days that CV19 is most contagious just after developing significant symptoms but before progression and also that reinfection is looking very unlikely or impossible (they gave macaque monkeys CV19, let them get over it and they couldn't reinfect them despite trying to). The whole thing could be a dumb idea but the paper and discussion seemed relevant enough to bring to people's attention because a lot of engineers are talking about designing DIY ventilators which seems a lot harder and even at 'maker' speed may not arrive fast enough in volume should the very worst happen in some areas.
