From the perspective of a former VFR Chart editor at Jeppesen, I'd consider leaving a SPB off a chart for the purpose of de-cluttering
a bit negligent.
But:
Usually there is an accessible "Revisions" list, showing the changes from one edition of a chart to the next.
Technically, you cannot change anything of significance on a chart without some sort of reason.
When clicking on the little square blue quadrant at 097R/1.3NM from TEB, I
do open the airport in the A/FD, though.
The Symbol of the SPB may have been replaced with this?
Consider that these charts are created in categorized layers, the matters of higher importance
print over the matters of lower importance.
IOW's the seaplane anchor symbol may be on a lower significance level for printing. There's obstacles and stuff, most of these print no matter what/ where. The editor
may not relocate obstacles in favor of lower safety significance information disseminated on the chart. Pointing to it by arrow may be an option, but in this case, not worth it.
To verify this thesis, look to the right towards "Evers (6N6)" SPB and note that the anchor is cut in place of the airport square. An obstacle is very close to Little Ferry, very much likely printing on a higher level.
If the editor of the chart finds this acceptable, that's how it goes to print.
Definitely prudent, considering how overloaded that part of the chart is naturally, and how little actual seaplane traffic there may be.
Here's the website where you can open that chart:
