No. You don't even NEED a timer in a multitasking system!
All you need is a source of asynchronous "events". E.g.,
receipt of a character on a UART, an ethernet packet on a NIC,
etc.

As was apparent in the MTX example I posted, previously.
But, the granularity of that time is under the arbitrary control
of the other tasks in the system, regardless of the needs or desires
of the task *utilizing* it (i.e., a task unconcerned with "time"
can introduce skews in the other tasks's notion of time AT IT'S
PEROGATIVE.

Semaphores are only required when that form of synchronization
is required.
task1()
blink indicator #4
task2()
play musical melody
task3()
display current time
None of this requires a semaphore. Yet, can exploit a preemptive
environment to ensure no task starves another.

Have you designed anything of significant complexity relying on a purely
cooperative implementation? How did you prove the performance and correctness
of the system? Did you consider every possible interaction of "yields"
and verify that all tasks still met their performance goals? Or, did you
rely on a Monte Carlo simulation?
Note, you said "no advantage at all". I can *prove* that a given thread
of code WILL execute and how long it will take to execute in every possible
scenario -- without having to walk through all other tasks wondering when
and where they will choose to yield() and how those IN CONCERT (not just a
single task) will affect the remaining tasks in the system

It does exactly what multitasking is designed to do: allow you
to decompose a problem into independant, concurrent tasks.
Instead of a spaghetti bowl of tasks writhing to compete cooperatively.

How does an event raised in an ISR *voluntarily* cause the currently
executing task to reschedule -- NOW, not when it decides it's convenient
for it?

I suspect you've not designed many "complex" systems, then.
"Many systems" doesn't speak to their complexity.
How do you handle updating a video display (synchronizing the display
update with the display refresh to eliminate visual artifacts)?
*While* receiving network packets. And, digitizing incoming audio
for delivery over the network. And, reproducing audio that's coming
in over that network connection. And, sampling the voltage and current
to a 3-phase load that you're managing. And, decoding RFID fobs
that "happen" to present themselves.
And, wondering what will be ADDED to the mix before you're finished?
Do you spend every other instruction yielding? Checking the current
time to decide *if* you should probably yield? Asking those other
tasks if they would *like* you to yield? etc.
Or, do you throw everything into ISR's for fear that they might not,
otherwise, get done?
Or, overprovision the hardware so you have resources that you can waste?
Preemption gives you the ISR framework OUTSIDE of the (limited) ISR context.
The example above -- a distributed, interactive load monitoring/management
system (my project for the next month) is just a trivial one...
