I guess I am from the old days. For me MSO has had nothing in terms of needed improvements since about 1998. And thankfully I moved to Libreoffice before the ribbon bar and all the VBA issues with 2013. Libreoffice became usable about 2005. Yes it was Excel for me that was the last to go. Solver in particular. As far as VBA, I switched from that to python about 1998.
As far as dated. I think it depends on who you think defines the standard . For me that is not MS.
