B Hubble breaks the distance record with a redshift of 11.1

Hubble breaks the distance record, with a large jump to a redshift of 11.1
Does this mean that some of theories need revision? We do not appear to reaching a limiting value!http://sci.esa.int/hubble/57530-hubble-breaks-cosmic-distance-record-heic1604/

Our current theories do not predict any "limiting value" for redshift. We have already measured a redshift much larger than 11.1: the redshift of the CMB, which is about 1000. This is just the record for the measured redshift of a single object.

[Btw, if you label a thread as "A", that implies that you have a graduate level understanding of the subject matter. This question is really a "B" question, and I have relabeled the thread accordingly.]

Thanks for replies guys.

I know the CMBR redshift is ~1000, but I was expecting to see a tangential limiting value for galaxy redshift at some point. I guess we need more measurements? Hopefully I will still be here to see the JWST measurements.

Btw I am a Physics Grad, just a very long time ago, specializing in Radio and Microwave Frequencies. Worked on Cyclotrons, Plasma Generators and 3G Transmitters mainly, for nearly 40 years.
But point taken, Cosmology was not a course I could take back then, even though it is one of the most interesting subjects for me now.
