Dear BIDS experts,
I'm a little bit confused about the naming of coordinates related files for https://bids-specification.readthedocs.io/en/v1.2.1/04-modality-specific-files/03-electroencephalography.html#coordinate-system-json-_coordsystemjson

For the data and the channels the template is

sub-<label>[_ses-<label>]_task-<label>[_run-<index>]_eeg

But for the electrodes, the task entity is missing while acquisition appears:

[sub-<label>[_ses-<label>][_acq-<label>][_run-<index>]_electrodes

And for coordinates run disappears:

[sub-<label>[_ses-<label>][_acq-<label>]_coordsystem

Is this naming inconsistencies are intended, and what the reason behind it?
