I have been using the QSFP-100G-CWDM4 2k optics for within rack/DC for a couple of years now. They are about the same price as SR optics but allow the use of simple duplex single mode patches without blasting 10K optics at each other over a 2M patch. Never had one fail or any compatibility issues.
Our use of multi-mode fibre is historical, from the days when vendors sold line cards that were mode-fixed and not pluggable. The installed base is so large that it's just easier to carry on with multi-mode for in-rack cabling, where it's needed.
